Consider the three prismatic beams with the clamped supports P, Q, and R as shown in the figures.

Diagram for Civil Engineering question 32

Given that the modulus of elasticity, E is 2.5×10⁴ MPa; and the moment of inertia, I is 8×10⁸ mm⁴, the correct comparison of the magnitudes of the shear force S and the bending moment M developed at the supports is

Your answerChoose one option.

S_P < S_Q < S_R; M_P = M_Q = M_R

S_P = S_Q > S_R; M_P = M_Q > M_R

S_P < S_Q < S_R; M_P = M_Q = M_R

S_P < S_Q < S_R; M_P < M_Q < M_R

Consider the following statements: P. Walls of one brick thick are measured in square meters. Q. Walls of one brick thick are measured in cubic meters. R. No deduction in the brickwork quantity is made for openings in walls up to 0.1 m² area. S. For the measurement of excavation from the borrow pit in a fairly uniform ground, deadmen are left at suitable intervals.

For the above statements, the correct option is

Your answerChoose one option.
