Question

For the following 10 questions, indicate if the statement is true or false by circling T or F. Provide any explanation and assumptions if needed. (1) T or F: No shear stress can occur on the planes carrying max and min normal stress. 2) T or F: If a material element is in plane stress, two normal stress components are always equal to each other if this is the plane of maximum shear stress. (3) T or F: No normal stress can occur on the planes carrying max and min shear stress, (4) T or F: Maximum shear stress in a uniaxially loaded member is zero. (5) T or F: Superposition of normal and shear stresses will always remain elastic if each of the stresses does not exceed the yield point. (6) T or F: Maximum shear stress and minimum normal stress occur on mutually orthogonal planes (7) T or F: Maximum normal stress and strains always occur on the same planes. (8) T or F: Both maximum shear stress and strains always occur on the same planes. (9) T or F: A small additional compression, which is normal to a uniaxial tensile load, increases the maximum shear stress in the member. (10) Tor F: A small additional tension, which is normal to a uniaxial tensile load, increases the maximum shear stress in the member
