Question 2
The maximum strain energy corresponding to the stress at the elastic limit is known as ____
Question 3
In the arrangement as shown in the figure, the stepped steel bar ABC is loaded by load P. The material has young’s modulus E= 200 GPa and the two portions AB and BC have area cross section 1cm2 and 2cm2 respectively. The magnitude of load P required to fill up the gap of 0.75 mm is
Question 4
