1. A simply supported beam carries varying load from zero at one end and w at the other end. If the length of the beam is a, the maximum bending moment will be
2. There are two hinged semicircular arches A, B and C of radii 5 m, 7.5 m and 10 m respectively and each carries a concentrated load W at their crowns. The horizontal thrust at their supports will be in the ratio of
3. If E, N, K and 1/m are modulus of elasticity, modulus of rigidity. Bulk modulus and Poisson ratio of the material, the following relationship holds good
4. Two bars, one of steel and the other of copper having areas of cross-sections As and Ac, coefficient of expansion ?s and ?c and Young's Modulii Es and Es are rigidly connected together at the ends and subjected to temperature change of t°. If the length of the bars initially is L, the final extension ? of the two bars at t° temperature is given by
6. Pick up the correct statement from the following:
Options
A. The bending moment which when acting alone would produce the maximum stress equal to the major principal stress caused by combined bending and torsion, is called equivalent bending moment
B. Mcg = (MM2 + r2) where letters carry their usual meanings
C. Tcp = m2 + T2 where letters carry their usual meanings
D. The torque which when acting alone would produce maximum shear stress equal to the maximum shear stress caused by the combined bending and torsion, is called equivalent torque
