The shape factor of standard rolled beam section varies from 1.30 to 1.40 1.40 to 1.50 1.10 to 1.20 1.20 to 1.30 TRUE ANSWER : ? YOUR ANSWER : ?
The ratio of the length and depth of a simply supported rectangular beam which experiences maximum bending stress equal to tensile stress, due to same load at its mid span, is 1/2 1/4 2/3 1/3 TRUE ANSWER : ? YOUR ANSWER : ?
A compound bar consists of two bars of equal length. Steel bar cross -section is 3500 mm²and that of brass bar is 3000 mm². These are subjected to a compressive load 100,000 N. If Eb = 0.2 MN/mm² and Eb = 0.1 MN/mm², the stresses developed are: b = 6 N/mm² s = 12 N/mm² b = 5 N/mm² s = 10 N/mm² b = 8 N/mm² s = 16 N/mm² b = 10 N/mm² s = 20 N/mm 2 TRUE ANSWER : ? YOUR ANSWER : ?
