A straight ladder is leaning against the wall of a house. The ladder has rails 4.90 m long, joined by rungs 0.410 m long. Its bottom end is on solid but sloping ground so that the top of the ladder is 0.690 m to the left of where it should be, and the ladder is unsafe to climb. You want to put a flat rock under one foot of the ladder to compensate for the slope of the ground. (a) What should be the thickness of the rock? (b) Does using ideas from this chapter make it easier to explain the solution to part (a)? Explain your answer.
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.

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?
. A carpenter and his assistant are to carry a uniform wooden beam, which is 6 m long
and weighs 100 kg, on their shoulders. Both men are of the same height so that the
beam is carried horizontally. However, the carpenter is the stronger of the two and
wishes to bear 50% more of the weight of the beam than his assistant. If one end of
the beam is placed on the assistant's shoulder, how far from the other end of the beam
should the carpenter put his shoulder?
