A simply supported beam of span L carries a concentrated load W at its midspan. If the width b of the beam is constant and its depth is varying throughout the span, then what should be its midspan depth, when design stress is f?
A beam of Tsection has I = 1200 cm^{4} and depth = 12 cm. Flange of the section is in compression. If the maximum tensile stress is two times the maximum compressive stress, what is section modulus in compression?
The width of a beam of uniform strength having a constant depth d, length L, simply supported at the ends with a central load W is
A beam of rectangular crosssection is 100 mm wide and 200 mm deep. If the section is subjected to a shear force of 20 kN, the maximum shear stress is
The ratio of the flexural strengths of two square beams one placed with two sides horizontal and the other placed with one diagonal vertical and other horizontal is
The modular ratio of the materials used in the flitched beam is 10 and the ratio of the allowable stresses is also 10. Four different sections of the beam are: shown in the given figures. The material shown hatched has larger modulus of elasticity and allowable stress than the rest.
Which one of the following statements is true for the beam under consideration ?
