A simply supported beam of span L Carries a concentrated load W at its mid span. The maximum bending moment M is

In rolled steel I beams, shear force is mostly resisted by

The maximum shear stress in a rectangular beam is

If E is young’ modulus and I is moment of inertia, then the expression  at any section for a beam is equal to

If the BMD for a simply supported beam is as shown below, the load on the beam will be

A steel bar ABC of uniform cross-section 100 mm² is suspended vertically and loaded as shown in the figure. If the lower end of bar C does not move when loads are applied (neglect self-weight), then the value of force P is (E_s=200 kN/mm²)

A given determinate truss is loaded with gravity loads. Under these loads different nodes undergo deflection horizontally and vertically. Thereafter the truss is subjected to a temperature drop of 50°C in the lower chord only. The coefficient of expansion or contraction =11.7x10^-6/°C . Which of the following statements is true?

The phenomenon of slow growth of strain under a steady stress is called:

Maximum deflection of a cantilever due to pure moment ‘M’ at its free end, is:

The ratio of modulus of rigidity to modulus of elasticity for a Poisson’s ratio of 0.25 would be:
