For the following questions answer them individually
Assertion (A) : The preferred cross-section of a beam subjected to transverse loading is I section.
Reason (R) : Section Modulus of I section is low
The cross-section of a member is subjected to a uniform shear. The strain energy stored per unit volume is equal to (G = modulus of rigidity)
Figures A,B,C and D are bending moment distribution of a simply supported beam for some particular shear stress distribution. which figure is the correct bending moment diagram corresponding to the shear stress distribution given below :
A uniform simply supported beam of span (l) carries a point load (W) at the Centre. The downward deflection at the centre will be
The power transmitted by a circular shaft rotating at N rpm under action of Torque T is:
