You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the Ti-6Al-4V…

A nearsighted eye is corrected by placing a diverging lens in front of the eye. The lens will create a virtual image of a distant object at the far point (the farthest an object can be from the eye and still be in focus) of the myopic viewer where it will be clearly seen. In the traditional treatment of myopia, an object at infinity is focused to the far point of the eye. If an individual has a far point of 39.5 cm, prescribe the correct power of the lens that is needed. Assume that the distance from the eye to the lens is negligible.

to identify the optimum air-fuel ratio for the combustion process in a boiler under
varying conditions of air supply and quality of fuel. The study would involve
design of experiments, data collection and analysis, simulation of the different
variables and validation of the optimum parameters. There is a lot of pressure to
improve the energy efficiency as there is a forecast of fuel price rise in the
forthcoming month.

horsepower. In mathematical
terms, one horsepower is the
power needed to move 550
pounds one foot in one
second, or the power needed
to move 33,000 pounds one

Learning Goal:
To learn to apply the method of joints to a truss in a systematic way and thereby find the loading in each member of the truss.
In analyzing or designing trusses, it is necessary to determine the force in each member of the truss. One way to do this is the
method of joints. The method of joints is based on the fact that if the entire truss is in equilibrium, each joint in the truss must also be
in equilibrium (i.e., the free-body diagram of each joint must be balanced).
Consider the truss shown in the diagram. The applied forces are P₁ = 630 lb and P₂ = 410 lb and the distance is d = 8.50 ft.

Learning Goal:
To use equilibrium to calculate the plane state of stress in a rotated coordinate system.
In general, the three-dimensional state of stress at a point requires six stress components to be fully described: three normal stresses and three shear stresses (Figure 1). When the external loadings are coplanar, however, the resulting internal stresses can be treated as plane stress and described using a simpler, two-dimensional analysis with just two normal stresses and one shear stress (Figure 2). The third normal stress and two other shear stresses are assumed to be zero.
The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are given in one coordinate system (Figure 3), the equivalent stresses in a rotated coordinate system (Figure 4) can be calculated using the equations of static equilibrium. Both sets of stresses describe the same state of stress.
The stresses σx′and τx′y′ can be found by considering the free-body…

Learning Objectives: This problem builds on the pump examples we have been doing, but is meant to help
you learn to do proofs in a step by step fashion. Can you generalize intuition from a simple example?
We consider a system of reservoirs connected to each other through pumps. An example system is shown
below in Figure 1, represented as a graph. Each node in the graph is marked with a letter and represents a
reservoir. Each edge in the graph represents a pump which moves a fraction of the water from one reservoir
to the next at every time step. The fraction of water moved is written on top of the edge.

Learning Goal:
To use transformation equations to calculate the plane state of stress in a rotated coordinate system.
The normal and shear stresses for a state of stress depend on the orientation of the axes. If the stresses are
given in one coordinate system (Figure 1), the equivalent stresses in a rotated coordinate system (Figure 2) can
be calculated using a set of transformation equations. Both sets of stresses describe the same state of stress.
In order to use the transformation equations, a sign convention must be chosen for the normal stresses, shear
stresses, and the rotation angle. For the equations below, a positive normal stress acts outward on a face. A
positive Try acts in the positive y-direction on the face whose outward normal is in the positive x-direction. The
positive direction for the rotation is also shown in the second figure.
The stresses in the rotated coordinate system are given by the following equations:

Question 3. The purchase price of a natural gas-fired commercial boiler (capacity X) was $181,000 eight years
ago. Another boiler of the same basic design, except with the capacity 1.42X, is currently being considered for
purchase. If it is purchased, some optional features presently costing $28,000 would be added for your
application. If the cost index was 162 for this type of equipment when the capacity X boiler was purchased and
is 221 now, and the applicable cost capacity factor is 0.8, what is your estimate of the purchase price for the
new boiler?

A. A customer asked you to explain your choice of a temperature sensor that you used for his PCB.
Initially, there were two sensor options. To compare between them, you decided to test their accuracy
and precision. Accuracy of a sensor is a measure of how near its reading is to the real value, the nearer
the measured value to the real value the better. While precision is a measure of how widely spread the
readings of a sensor are [relative to each other] when measuring the same variable, the narrower the
spread the better. So, you tested the two sensors by measuring the same temperature, which was 100
C of boiling water, and you recorder the following 10 measurements of each sensor. Which Sensor has
higher accuracy, and which one has higher precision.

Learning Goal:
To find the acceleration a of a particle of mass m, we use Newton's second law:
Fnet = ma, where Fnet is the net force acting on the particle.
To find the angular acceleration cx of a rigid object rotating about a fixed axis, we can use a
similar formula: Thet = Ia, where Thet = ΣT is the net torque acting on the object and I
is its moment of inertia.
In this problem, you will practice applying this formula to several situations involving
angular acceleration. In all of these situations, two objects of masses m₁ and m2 are
attached to a seesaw. The seesaw is made of a bar that has length 1 and is pivoted so that
it is free to rotate the vertical plane without friction.
You are to find the angular acceleration of the seesaw when it is set in motion from the
horizontal position. In all cases, assume that m₁ > m₂, and that counterclockwise is
considered the positive rotational direction.

Learning Goal:
To calculate the normal and shear stresses at a point on the cross
section of a column.
A column with a wide-flange section has a flange width b = 250 mm , height k = 250 mm , web thickness to = 9 mm , and flange thickness t; = 14 mm (Figure 1).
Calculate the stresses at a point 65 mm above the neutral axis if the section supports a tensile normal force N = 2 kN at the centroid, shear force V = 5.8 kN , and
bending moment M = 3 kN - m as shown (Figure 2).
The state of stress at a point is a description of the normal and shear
stresses at that point. The normal stresses are generally due to both
internal normal force and internal bending moment. The net result can
be obtained using the principle of superposition as long as the
deflections remain small and the response is elastic.
Part A- Normal stress
Calculate the normal stress at the point due to the internal normal force on the section.

- You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial weight bearing activities. Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the yield stress for the Ti-6Al-4V…arrow_forwardYou are assigned as the head of the engineering team to work on selecting the right-sized blower that will go on your new line of hybrid vehicles.The fan circulates the warm air on the inside of the windshield to stop condensation of water vapor and allow for maximum visibility during wintertime (see images).

- A nearsighted eye is corrected by placing a diverging lens in front of the eye. The lens will create a virtual image of a distant object at the far point (the farthest an object can be from the eye and still be in focus) of the myopic viewer where it will be clearly seen. In the traditional treatment of myopia, an object at infinity is focused to the far point of the eye. If an individual has a far point of 39.5 cm, prescribe the correct power of the lens that is needed. Assume that the distance from the eye to the lens is negligible.arrow_forwardQUESTION 1 In 2020, the world faces a critical health issue called Covid-19.
