S O M Short Interview Question Answers on Modulus, factor of safety and SFD AND BMD Q. What is Young’s modulus? What is its symbol? What are its units? A. It is a ratio of tensile stress to tensile strain and also compressive stress to compressive strain. Its symbol is ‘E’. E= σt / εt […]
Shear Force and Bending Moment Diagram—3– Utility and Final Selection of the Beam Utility of SFD and BMD Maximum shear force will be used to design the beam. Design means (i) Select the material of construction (ii) Select the method of manufacture (iii) To select the shape and contour of the beam (iv) To find […]
Shear Force and Bending Moment Diagrams–2– Drawing of SFD and BMD SHEAR FORCE ON A BEAM It is the NET VERTICALLY UPWARDS OR NET VERTICALLY DOWNWARDS FORCE on one side of the point being considered on the beam. Only after finding the shear force at various points on the beam, the S.F.D. can be drawn. From the […]
SHEAR FORCE AND BENDING MOMENT DIAGRAMS (SFD and BMD) FOR BEAMS- 1 –INTRODUCTION DEFINITION OF A BEAM Beam is a most important member of a machine, vehicle or a structure.
