Chapter 12, Problem 9P

A flexible chain weighing 40.0 N hangs between two hooks located at the same height (Fig. P12.9). At each hook, the tangent to the chain makes an angle θ = 42.0° with the horizontal. Find (a) the magnitude of the force each hook exerts on the chain and (b) the tension in the chain at its midpoint. Suggestion: For part (b), make a force diagram for half of the chain.

A 15 kg monkey climbs a uniform ladder with weight 1.2 *10^2 N and length L=3.00 m. The ladder rests against the wall and makes an angle of theta= 60.0 degrees 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. HInt : Draw a force diagram for the ladder and the normal forces from the ground and wall acting on the ladder.  A) find the tension in the rope when the monkey is two-thirds of the way up the ladder. B) The rope is frayed and can support a maximum tension of only 80N. Find the maximum distance that the monkey can climb up the ladder before the rope breaks. C) If the horizontal surface were rough and the rope were removed, how would your analysis of the problem change? What other information would you need to answer parts (a) and (b)
A 24 kg rectangular 4.00 m x 3.00 m rectangular sign is suspended from a horizontal 6.00 m long rod with a 5 kg mass as indicated in the figure. The left end of the rod is supported by a hinge, and the right end is supported by a thin cable making a 30.0° angle with the vertical. Draw a free body diagram and calculate the tension T in the cable. The thin cable breaks if it is pulled by more than 200 N. Show than in the present situation the cable can not support the sign without breaking. Show the cable is able to support the load if it is attached higher up such that it makes an angle of 20.0° angle S0.0 CE CREAM SHOP with the vertical.
