Answer question Q1
Question One: Derive expressions for determining the change in length for the following bodies P4 P b. b2 dx Cross-section Cross-section Question Two A steel flat of thickness 10 mm tapers uniformly from 60 mm at one end to 40 mm at other end in a length of 600 mm. If the bar is subjected to a load of 80 kN, find its extension. Take E = 2 x 10 MPa. What is the percentage error if average area is used for calculating extension? Question Three: Derive expressions that shows 1) Relationship between modulus of elasticity and modulus of rigidity 2) Relationship between modulus of elasticity and bulk modulus
