Strength of Materials - Section 1 (5)

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

In case of an eccentric loading on a bracket subjected to moment M, the tangential force developed in any rivet, at right angles to its radius vector r is

In the cantilever truss as shown in below figure, the horizontal component of the reaction at A, is

If the shear force along a section of a beam is zero, the bending moment at the section is

A closely coiled helical spring of radius R, contains n turns and is subjected to an axial load W. If the radius of the coil wire is r and modulus of rigidity of the coil material is C, the stress developed in the helical spring is

If two forces acting at a joint are not along the straight line, then for the equilibrium of the joint

A beam of length L is pinned at both ends and is subjected to a concentrated bending couple of moment M at its centre. The maximum bending moment in the beam is

A uniform girder simply supported at its ends is subjected to a uniformly distributed load over its entire length and is propped at the centre so as to neutralise the deflection. The net B.M. at the centre will be
