What is the work done by the weight of the 1-kg pendulum as it rotates from the horizontal position to the vertical position? Hint: All the mass is concentrated at the tip of the pendulum, indicating that this is a particle problem. A) 7.36 N.m B) 3.68 N m C) -3.68 Nm D) 0 N.m Point B on the rod has a velocity of 10 m/s decreasing at 2 m/s² to the right. Where is the instantaneous center of zero velocity (IC) for the rod? A) Point A B) Point B C) Point C D) Point D 14--- 4m A) maximum C) zero If a rigid body is rotating about a fixed axis, the mass moment of inertia about its rotating axis is always 075 B) minimum D) none of the above 5 m What is the work done by the weight of the 1-kg pendulum as it rotates from the horizontal position to the vertical position?
