Chapter 5, Problem 5.5.2P
A steel wire (E = 200 GPa) of a diameter d = L25 mm is bent around a pulley of a radius i/o = 500 mm (see figure),
- What is the maximum stress true in the wire?
- By what percent docs the stress increase or decrease if the radius of the pulley is increased by 25%?
- By what percent docs the stress increase or decrease if the diameter of the wire is increased by 25% while the pulley radius remains at Rq = 500 mm?

The hoist consists of a single rope and an arrangement of
frictionless pulleys as shown. If the angle 0 = 59°, determine
the force that must be applied to the rope, Frope, to lift a
load of 4.4 kN. The three-pulley and hook assembly at the
center of the system has a mass of 22.5 kg with a center of
mass that lies on the line of action of the force applied to the
hook.

A block of mass m hangs from the end of bar AB that is 7.2
meters long and connected to the wall in the xz plane. The
bar is supported at A by a ball joint such that it carries only a
compressive force along its axis. The bar is supported at end
B by cables BD and BC that connect to the xz plane at
points C and D respectively with coordinates given in the
figure. Cable BD is elastic and can be modeled as a linear
spring with a spring constant k = 400 N/m and unstretched
length of 6.34 meters.
Determine the mass m, the compressive force in beam AB
and the tension force in cable BC.
