A wooden plank of length L and mass M is placed against a wall and connected to a rope at an angle 0 that holds it in place. This is depicted in the figure below. The rope can handle a maximum tension of T before it breaks. A sign with mass m is attached to the plank at x, which is 2/3 L distance from the wall. L= 2.00 m M= 0.500 kg 0 = 30.0° T= 1.50 × 102 N a) Draw all the forces on a diagram. b) What is the maximum mass that can be supported? c) What is the coefficient of static friction between the wall and the plank?

A 10.0-kg monkey climbs a uniform ladder with weight 1.20 102 N and length L = 3.00 m as shown in Figure P12.14. The ladder rests against the wall and makes an angle of = 60.0 with the ground. The upper and lower ends of the ladder rest on frictionless surfaces. The lower end is connected to the wall by a horizontal rope that is frayed and can support a maximum tension of only 80.0 N. (a) Draw a force diagram for the ladder. (b) Find the normal force exerted on the bottom of the ladder. (c) Find the tension in the rope when the monkey is two-thirds of the way up the ladder.

A uniform horizontal strut weighs 400.0 N. One end of the strut is attached to a hinged support the wall and the other end of the strut is attached to a sign that weighs 200.0 N The strut is also supported by a cable attached between the end of the strut and the wall. Assuming that the entire weight of the sign is attached at the very end of the s find the tension in the cable and the force at the hinge of the strut.
