The uniform 225lb crate is supported by the thin homogeneous

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 0 = 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 cantered on the 6-ft platform, and friction is sufficient to keep the crate motionless relative to the platform. Be careful with the location of the resultant normal force beneath the crate.)
