INTERVIEW SHORT QUESTION ANSWERS -Simple stresses and strains-1 Q1. Write the relationship between true strain and conventional strain as well as relationship between true stress and conventional stress. A. When a tensile load is applied to a ductile material, its length increases and area of cross section decreases. When load is applied beyond a certain limit, […]
INTERVIEW SHORT QUESTION ANSWERS -Torsional moment Q1Find the ratio of the torsional moments of resistance of a solid circular shaft of diameter ‘D’ and a hollow circular shaft having external diameter ‘D’ and internal diameter ‘d’. A. Torsional moment is torque’ T ’. Tsolid = (πD3/16) z Thollow = π(D4—d4)/16 D) z Ratio Tsolid / […]
INTERVIEW SHORT QUESTION ANSWERS–Simple stresses-2 Q1. What is meant by SOM? One material has different strengths under various types of loads. For example: concrete has strength in compression as 30 N/mm2. In tension, it has strength of 3 N/mm2. It is better to use concrete under a compressive load and NOT under a tensile load. […]
Short Interview Question Answers On bending DEFINITION OF BENDING Bending is a part of a circular deformation. Initially straight member becomes like a bow or an arc. ASSUMPTIONS USED IN DERIVATION OF BENDING EQUATION (i) Beam is initially straight. (ii) Beam is homogeneous i.e. composition is same throughout. (iii) Material is continuous i.e. no voids or […]
Interview Short Question Answer -Bending Q1. A beam of square section with side ‘a’ is used with its diagonal horizontal. Find the section modulus of the beam. A. There will be one triangle above and another below the horizontal diagonal. The moment of inertia of one triangle about the base is bd3/12= a4/12. Therefore the […]
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/kmin ratio. This ratio is called the slenderness ratio. In this, Le is the […]
Interview Short Question Answers on Bernoulli Equation 1. What is Bernoulli equation? Bernoulli equation is the mathematical form for the law of conservation of energy for a flowing liquid. p1/ ρ+ ρ v12/2 + z1 = p2/ ρ + ρ v22/2 + z2 = Constant Flow work + kinetic energy + Potential energy = […]
Short Interview Question Answers on Stresses Q. Define 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 throughout in […]
Short Interview Question Answers on simple stresses What is meant by Strength of Materials? This subject tells which materials are strong in tension/compression/bending/torsion/buckling loads. Hence depending upon the application, one can select the material for that application. Application includes chair, table, rod, shaft or any item one can think of. The selection is possible after […]
Short Interview Question Answers on different loads 21. What are various types of forces? Two types of forces: Constant magnitude and variable magnitude. Examples of Constant magnitude forces: Weight force acting vertically downwards Examples of variable magnitude forces: Pressure force, Wind force, Inertia force, Centrifugal force, Thermal force, Seismic force, Frictional force, Snow load […]
