CWB Level 2 Study Questions rev 1 | Questions and Correct | Latest Update 2024/2025 | Graded A+ When a metal is subjected to an electrical external force(load) the force will be resisted by internal forces within the metal, this is called? - Answer -Stress and strain What is the equation for stress-force - Answer -Load/area Which 3 ways can a load not act on a cross-sectional area in a body. - Answer -Tension, compression, and shear If an object is twisted it is said to be in? - Answer -Torsion What else does torsion produce - Answer -Shear stresses The type of stress depends on? - Answer -The orientation of stress that the section surface being considered has with the direction of stress What term is used to describe a body in a measurement of the change in dimensions due to the application of an applied load - Answer -Strain ( Ductility) What is the equation for strain - Answer -Extension/original length What can be tensile or compressive depending on whether the body increases in length or decreases. - Answer -StrainWhat direction is affected in the stress and strain when a bar is loaded - Answer -Axial direction (along its length) When a specimen stretches it becomes thinner and suffers a strain in what direction - Answer -Transverse direction (across the thickness) Which type of stress occurs in only one direction but produces strains in other? Does this occur in thin or thick sections - Answer -Plane stress and it occurs in thin sections The relationship between E and the stress/strain is called what? - Answer -Hooke's law
