CWB Module 12 When a metal is subjected to load, it will be resisted by internal forces within the metal. The intensity of these forces through a given plane is known as? Stress Select the three ways in which a load can act on a cross-sectional area in a body. A) Perpendicular B) Tension C) Angular D) Compression E) Helixial F) Shear B) Tension, D) Compression, F) Shear Brainpower Read More True or False "Strain is the extension divided by the original length" True The modulus of elasticity, E, for steel is usually taken as: A) 2,000 MPa B) 200,000 MPa C) 200 MPa D) 2,000,000 MPa E) 29,000 MPa B) 200,000 MPa or 29,000,000 PSi If a plot of stress against strain is made for a bar that undergoes plastic deformation, the stress at which a permanent set is first recorded when the bar is unloaded is known as: A) permanent set. B) Strain. C) The elastic limit. D) The proportional limit C) The elastic limit. True or False? Stress is the load divided by the original cross-sectional area" True To carry out tensile tests, special machines are needed to exert the necessary force. They are generally two types Mechanical and Hydraulic
