‘W’ kN acting at L/4’ from both ends. The shear force at the mid point of the beam

will be :

ॐ A ‘T" section is used as simply supported beam, it is subjected to a uniformly
distributed load throughout the span. The maximum bending stress will occur at :
(ಹ) Top of the section
(B) Centre of gravity of the section
(C) Bottom of section
(D) At the junction between flange and the web of the section

4. A cantilever beam of span ‘L’ units is subjected to a concentrated load of ‘W’ kN at the
free end. The cross section of the beam is rectangular with breadth b’ units and
depth ‘d’ units. If the modulus of elasticity of the beam material is ‘E’, the ratio of
maximum deflection to maximum bending stress is :
