please i dont have much time solve fast as you can When the angle θ = 90 °, the BE hydraulic cylinder applies a vertical force (F = 3330 N) Newtons to the platform. The mass of the crate is 200 kg and the angular velocity (ω) of AB is 7 (rad / s). First, treat the box and platform as a single body to find the following: The amount of reaction forces at points B and D. Acceleration of the center of the box aG in the x and y direction. Second, after finding the previous requirements, find the following for the platform only: The force of reaction from the box to the platform (Normal force). Minimum static friction coefficient (μs) to ensure the box does not slip. Note: Neglect the weight of the platform and objects AB and CD.

To use the equations of equilibrium to analyze a system containing a wedge and to determine the necessary applied force to introduce motion into the system. The crate shown is held against wedge B by a spring. The spring is 96.0% of its original uncompressed length l= 3.00 m, and the spring constant is given as k = 1750 N/m. The coefficient of static friction at all contacting surfaces is ls = 0.150. The mass of the crate is m = 23.0 kg . The angle is 0 = 13.0°. Neglect the mass of the wedge. Assume the crate only moves in the y direction and that wedge A cannot move. (Figure 1) Figure 1 of 1 В
