The axis of Earth makes a 23.5 angle with a direction perpendicular to the plane of Earth’s orbit. As shown below, this axis precesses, making one complete rotation in 25,780 y. (a) Calculate the change in angular momentum in half this time. (b) What is the average torque producing this change in angular momentum? (c) If this torque were created by a pair of forces acting at the most effective point on the equator, what would the magnitude of each force be?

The length of the ladder is 4.00 m. The mass is uniformly distributed along the length of the ladder, so its center of mass is at the geometric center of the ladder or at half its length as shown. The angle between the ladder and the floor is 0 = 32.7°. What is the magnitude and direction of the torque created by the mass of the ladder about a pivot point which is the point at which the ladder is touching the floor (a circle is on drawing to indicate the pivot point?
