The bent flat bar rotates about a fixed axis through point O. The angle can be found at any instant according to this relation 8 = π * sin(t), where 9 is in rad and it is in seconds. At this instant, determine the instantaneous velocity and acceleration of point A. Note: w=0, a = 0. Also, you must change the angle from (Degree) to (Rad) IM
