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 C

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.
