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. What should be
the thickness of the rock?

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.

The ladder just overhangs a plastic rain gutter, which we can assume to be frictionless, so the force from the gutter on the ladder acts perpendicularly to the ladder. As a result, the top of the ladder experiences a normal force at an angle, while the bottom of the ladder experiences both a vertical normal force and a horizontal friction force.
