A simply supported beam is subjected to a uniformly distributed load over its entire span. Which of the following statements is true?

For equal sectional area, arrange circular, square and I-section in the increasing order of their shear strength?

A square beam and a circular beam of the same material have the same strength against shear forces. What is the ratio of the side of the square to the diameter of the circle?

A symmetrical I-beam of flange width 100mm, web width 10mm, flange depth 10mm and web depth 150 mm is subjected to a shear force of 1000 N. What is the ratio of the shear stress at the top of the web and at the bottom of the top flange?

A rectangular beam of width 200 mm and depth 300 mm is subjected to a vertical shear force of 2000 N. What would be the ratio of the shear force taken by the top one third of the section to the bottom one third?

For a beam of rectangular section under bending, the shear stress across its depth varies:
