Within elastic limit, shaer stress is........... shaer strain.
The ratio of change in volume to the original volume is called
The ratio of the lateral strain to the linear strain is called :
The shear modulus of most materials with respect to the modulus of elasticity is
The thermal or temperature stress developed in a bar depends upon :
The thermal stress in a bar is ....... proportional to the change in temperature.
The thermal stress............ upon the cross-sectional area of the bar.
The ultimate tensile stress for mild steel is the ultimate compresive stress .
The maximum stress produced in a bar of tapering section is at :
The modulus of elasticity for mild steel is approximately equal to :
When a change in length take place, the strain is known as :
