a ladder whose length L is 12 m and whose mass is 45 kg rests against a wall. Its upper end is a distance h of 9.3 m above the ground, as in the Figure. The center of gravity of the ladder is one-third of the way up the ladder. A firefighter whose mass M is 72 kg climbs halfway up the ladder. Assume that the wall, but not the ground is frictionless. What forces are exerted on the ladder by the wall and by the ground?
1. A non-uniform is 4.5m long and weighs 640N. It is balance when a 270N weight is hung 0.800m from the light end of the bar and the bar is pivoted at its center. Where is the center of gravity of the bar? 2.Two workers carry a non-uniform beam weighing 730N. The beam is 2.6m long and its center of gravity is 1.1 m from one end.

The following figure shows a 4 m bar fixed to the wall through a hinge that rotates freely, but is tied to the wall at its other end so that the system is in equilibrium. If the bar weighs 40 N and the tension in the rope is 20 N, find the angle of inclination θ that the bar makes with the x-axis.
Consider the pulley system depicted in the figure. The block is prevented from moving by the applied force F. Assume the pulleys are massless and frictionless. An illustration shows a rectangular block of mass M suspended from a horizontal surface by a complex pulley system comprised of one large pulley, one small pulley, two short ropes, and one long rope. The pulleys are drawn such that the small pulley is some vertical distance below the large pulley and their axles are perpendicular to the page. The left side of the small pulley aligns vertically with the center of the large pulley. One of the short ropes suspends the block of mass M from the bottom of the small pulley's harness and has tension T5. The remaining short rope and the long rope are, respectively, anchored to the top and bottom of the large pulley's harness. This short rope has tension T4 and suspends the large pulley from the horizontal surface. The long rope extends from the large pulley and cradles the small…
