Two identical slender rods AB and BC, each of which has a mass m and length L The rods are connected by a pin at 8 and by the cord AC. The assembly rotates in a vertical plane under the combined effect of gravity and a couple M applied to rod AB. Consider that each rod has a moment of inertia of 1. Starting from rest at the position shown. 0 M L- B
Y O angular velocity=0 O the acceleration at point A is the same as the acceleration at point C O angular acceleration - 0 O when the whole body rotates by 30 degrees, the velocity of point B and C will be equal O angular velocity >0, but must be calculated from the information given above < Previous Next
