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](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F992c34b5-57e2-4b06-981c-1c704167be52%2Fabf76936-2081-44ec-a014-8d4c8f511aaa%2F1bcpdya_processed.jpeg&w=3840&q=75)
