Chapter 12, Problem 31P

A uniform board of length L and weight W is suspended between two vertical walls by ropes of length L/2 each. When a weight w is placed on the left end of the board, it assumes the configuration shown in Fig. 12.22. Find the weight w in terms of the board weight W.

A tightrope walker stands on a wire that is supported by a pole at each end. The tightrope walker creates a tension of 3.42 ✕ 103 N in a wire making an angle 6.2° below the horizontal with each supporting pole. Calculate how much this tension stretches the steel wire (in cm) if it was originally 16 m long and 0.50 cm in diameter. I asked this question THREE times and it was rejected the first two for being incomplete. It is not incomplete. There is no accompanying image. The third time, it was answered . . . incorrectly. I am very annoyed that I keep wasting my limited question attempts on ONE question that I am trying to understand how to do.
A cable used to lift heavy materials like steel I-beams must be strong enough to resist breaking even under a load of 1.7  106 N. For safety, the cable must support twice that load. (a) What cross-sectional area should the cable have if it's to be made of steel?   (b) By how much will a 7.0-m length of this cable stretch when subject to the 1.7  106-N load?
As part of an engineering design, a load of mass M2=10 kg is to be suspended from the far end of a beam of mass M1=8kg. A horizontal cable supporting the beam attaches to the beam at a distance of d=2m from a joint/hinge. The length of the beam is L=7m. The beam makes an angle of 55 degrees with the horizontal. M, 2 a. What magnitude of force should the cable be able to withstand in this setup? b. What magnitude of force should the joint/hinge be able to withstand in this setup?
