Chapter 13. Elasticity Photo © Vol. 10 PhotoDisk/Getty BUNGEE jumping utilizes a long elastic strap which stretches until it reaches a maximum length that is proportional to the weight of the jumper. The elasticity of the strap determines the amplitude of the resulting vibrations. If the elastic limit for the strap is exceeded, the rope will break.
Objectives: After completion of this module, you should be able to: • Demonstrate your understanding of elasticity, elastic limit, stress, strain, , and ultimate strength. • Write and apply formulas for calculating Young’s s modulus, shear modulus, , and bulk modulus. • Solve problems involving each of the parameters in the above objectives.
