ANSWER (a) AND (b) ONLY. SHOW COMPLETE SOLUTION.
The vertebra of the spinal column can support a maximum compressive stress of smax, before undergoing a compression fracture. Determine the smallest force P that can be applied to a vertebra, if we assume this load is applied at an eccentric distance e from the centerline of the bone, and the bone remains elastic. Model the vertebra as a hollow cylinder with an inner radius ri and outer radius ro.
The stepped rod is made up of two different materials A and B of lengths 80 cm and 1.2 m respectively. The diameters of materials B and A are 2.5 and 3.5 cm respectively. The modulus of elasticity of materials A and B are 250 and 150 GPa respectively. The elongation of the rod is the same for both the materials. A total tensile load of 40 kN is applied to both the materials A and B together. Calculate the load in each material.
