A horizontal L=1.5 m long mb=D14 kg uniform bar is hinged on the left end and pulled at the right end by a cable. The cable makes 31° angle with horizontal. A 15 kg store sign is suspended below the bar at d=0.20 m from the right end. Find the magnitude of vertical hinge force.

A uniform ladder weighing 490 N rests against a frictioniess wall. The ladder has a length L = 14.0 m and makes a 59.0° angle with the horizontal ground. An 820 N firefighter has climbed d = 4.20 m along the ladder from the bottom. Find the coefficient of static friction Hs between the ladder and the ground. O 0.863 O 0.225 O 0.119 O 0.332 O 0.567

A uniform, 3.0 m, 1150 kg beam is hinged to a wall and supported by a thin cable attached 2.0 m from the free end of the beam (Figure 1). The beam is supported at an angle of 30.0 above the horizontal. Figure 40.0⁰ 30.0⁰ 1 of 1 2.0 m ▼ Find the tension in the cable.

A 400.0-N sign hangs from the end of a uniform strut. The strut is 4.0 m long and weighs 600.0 N. The strut is supported by a hinge at the wall and by a cable whose other end is tied to the wall at a point 3.0 m above the left end of the strut.
