Strength Of Materials
Strain energy is the
energy stored in a body when strained within elastic limits
energy stored in a body when strained upto the breaking of a specimen
maximum strain energy which can be stored in a body
proof resilience per unit volume of a material
The neutral axis of the cross-section a beam is that axis at which the bending stress is
zero
minimum

infinity
Euler's formula holds good only for
short columns
long columns
both short and long columns
weak columns
A steel bar of 5 mm is heated from 15° C to 40° C and it is free to expand. The bar Will induce
no stress
shear stress
tensile stress
compressive stress
The stress induced in a body, when suddenly loaded, is __________ the stress induced when the same load is applied gradually.
