1.
If a concrete column 200 x 200 mm in cross-section is reinforced with four steel bars of 1200 mm2 total cross-sectional area. Calculate the safe load for the column if permissible stress in concrete is 5 N/mm2 and Es is 15 Ec
2.
If normal stresses due to longitudinal and transverse loads on a bar are σ1 and σ2 respectively, the normal component of the stress on an inclined plane θ° to the longitudinal load, is
σ1 sin θ x σ2 cos θ
σ1 sin θ2 + σ2 cos2 θ
3.
A shaft subjected to a bending moment M and a torque T, experiences
maximum bending stress = 
maximum shear stress = 
both (a) and (b)
neither (a) nor (b)
4.
In the truss shown in given figure the force in member DC is
5.
If M, I, R, E, F, and Y are the bending moment, moment of inertia, radius of curvature, modulus of elasticity stress and the depth of the neutral axis at section, then
