Question: The 20-lb plate is mounted on the shaft AB so that the plane of the plate makes an angle = 30 with the vertical.

The 20-lb plate is mounted on the shaft AB so that the plane of the plate makes an angle θ = 30° with the vertical. If the shaft is turning in the direction shown with an angular velocity of 25 rad/s, determine the vertical reactions at the bearing supports A and B when the plate is in the position shown. A 18 in.. 0 = 30 6 in. 6 in. 18 in.

A 18 in.. 0 = 30 6 in. 6 in. 18 in. B
