36.

The bending moment diagram for a simply supported beam carrying a uniformly distributed load of

*w*per unit length, will be37.

The bending moment at the centre of a simply supported beam with a gradually varying load from zero at both ends to

*w*per metre at the centre is*wl*/4.38.

A body is subjected to a direct tensile stress of 300 MPa in one plane accompanied by a simple shear stress of 200 MPa. The maximum shear stress will be

39.

In a thick cylindrical shell subjected to an internal pressure (

*p*), the tangential stress is always a tensile stress where as the radial stress is a compressive stress40.

The horizontal thrust offered by the retaining wall on the retained material is (where

*w*= Specific weight of the retained material,*h*= height of retaining wall, and (φ) = Angle of repose of the retained earth)Quick links
