HINGED PLATE IN FREE FALL
HINGED PLATE IN FREE FALL
(OP)
HELLO ALL: This is a real problem. A uniform rectangular flat steel plate hinged on one side is held at an angle, theta (90<theta>0). The only force acting is earth's gravity. The plate is suddenly released and allowed to fall under th influence of gravity to the horizontal position. ignore friction in the hinge and wind resistance.
The center of gravity of the plate is not necessarily at the midpoint of the plate in the rotational plane. Thus it is distance "A" from the center of the hinge and distance "B" from the other end. It is centered in the direction looking into the paper.
Determine the angular acceleration and angular position as a function of time for the plate.

RE: HINGED PLATE IN FREE FALL
You have not given any information regarding the polar moment of inertia, which is required to solve any problem involving angular acceleration.
