The uniform 225-lb crate is supported by the thin homogeneous 40-lb platform BF and light support links

Question:

The uniform 225-lb crate is supported by the thin homogeneous 40-lb platform BF and light support links whose motion is controlled by the hydraulic cylinder CD. If the cylinder is extending at a constant rate of 6 in. /sec when θ = 75°, determine the magnitudes of the forces supported by the pins at B and F. Additionally, determine the total friction force acting on the crate. The crate is centered on the 6-ft platform, and friction is sufficient to keep the crate motionless relative to the platform.
