2–1. An air-filled rubber ball has a diameter of 6 in. If
the air pressure within it is increased until the ball’s
diameter becomes 7 in., determine the average normal
strain in the rubber.
e = Ans.
pd - pd0
pd0

7 - 6
6 = 0.167 in./in.
d = 7 in.

2–2. A thin strip of rubber has an unstretched length of
15 in. If it is stretched around a pipe having an outer diameter
of 5 in., determine the average normal strain in the strip.

2–3. The rigid beam is supported by a pin at A and wires
BD and CE. If the load P on the beam causes the end C to
be displaced 10 mm downward, determine the normal strain
developed in wires CE and BD.
