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?
