Multiple choice Questions (mcq) on Strength of Materials – On Bending and Shear Stresses in Beams and Buckling of Columns Bending of beam occurs under (a) Axial load (b) Transverse load (c) Direct load (d) None (Ans: b) Buckling of a column occurs under (a) Axial load (b) Transverse load (c) Direct load (d) None […]
Short Interview Question Answers on column and struts Q What is a column? It is a vertical member under an axial compressive load. Load may be axial or eccentric. It can be a short, medium or long column depending upon the Le/k ratio. It is called the slenderness ratio. In this, Le is the […]
Short Interview Question Answers on Stresses 11. What is a bending stress? What is its symbol? What are its units? Bending stress is caused due to load perpendicular to the length (lateral load) in a beam. Bending of beams causes both tensile and compressive stresses at the same time and these stresses are not constant […]
