Thin rubber strips are used to provide increasing resistance to orthopedic patients during large motion exercises.The sheets are 0.03125 in. thick and 3.00 in. wide. The rubber properties are E=120 psi and γ=0.47. One end of the strip is wrapped around the doorknob, and the other end is wrapped around the hand. The portion of the strip that elongates is approximately 18 in. What is the increase in force exerted with every 1 in. increase in length? If a force of 2lb is applied, what is the change in the strip's length and width?
