A rectangular bar is uniformly loaded axially with force per unit area `sigma` shown. Shown is a section `A A'` in the bar. Normal stress for the section is

"Stress is the force per unit area." Is it correct?

Braking froce per unit area of cross section of a wire is called

The breaking stress on a unit cross sectional area is

The breaking stress on a unit cross sectional area is

A rectangular bar is fixed to a hard floor. Height of the bar is h and its area in contact with the floor is A. A shearing force distorts the bar as shown. Prove that the work done by the shearing force is W = ((sigma^(2))/(2 eta)) xx volume of the bar. Here sigma is shear modulus of elasticity. Assume the deformation to be small.

The internal restoring force acting per unit area of cross-section of the deformed body is called
