1.

By applying the static equations

*i.e.*Σ*H*= 0, Σ*V*= 0 and Σ*M*= 0, to a determinate structure, we may determine2.

The general expression for the B.M. of a beam of length

*l*is the beam carries3.

The ratio of the length and diameter of a simply supported uniform circular beam which experiences maximum bending stress equal to tensile stress due to same load at its mid span, is

4.

If a solid shaft (diameter 20 cm, length 400 cm,

*N*= 0.8 x 10^{5}N/mm^{2}) when subjected to a twisting moment, produces maximum shear stress of 50 N/mm^{2}, the angle of twist in radians, is5.

The maximum B.M. due to an isolated load in a three hinged parabolic arch, (span

*l*, rise*h*) having one of its hinges at the crown, occurs on either side of the crown at a distanceQuick links
