Question

PLZ ANSWER THE QUESTION PROPERLY. ANSWER ALL THE THREE PARTS. SINCE THEY ARE OF SHORT ANSWER TYPE & THEY ARE PART OF SAME QUESTION

A rectangular beam is cut from a circular log of wood of diameter 'd'. Find the ratio of breadth to depth of rectangular beam for the strongest section in bending. b 1 h v2 Ans: Three beams have the same length, same allowable stresses and same bending moment. The cross section of the beams are circle, square and rectangle of depth twice the width. Find the weights of circular and square beams with respect to the rectangular beam. We W. Ans: WR = 1.26 1.4,- WR A beam is composed of 6 planks of 100mm wide and 20mm deep piled loosely one over the other to an overall depth of 120mm. Compare the strength of such a beam with that of a solid beam of the same overall dimensions. Ans: Strength of solid 9 = Strength of planks
