Question

True false:

1) When subjected to bending, a beam only develops normal stress in tension and compression

2)the shear flow is defined as an average force per unit length for each cross-section.

3)due to bending shear flow develops only along the beam length.

4)) shear center is defined as the point through which force can be applied without causing torsion

Fill in the blank:

the shear stress induced by bending in a beam is ............

Solve the question problem:

A bar of cross-section 54mm^2 and length 151mm is subjected to an axial load of 14KN. determine the normal stress (In MPA) developing in a bar?
