1. As a section cut in a prismatic bar varies from 0 = 0° to 180° at what values of 0 will the maximum values of normal stress and shearing stress occur, respectively? 2. Draw a generic stress element with no values, using only variables (0, for example) and arrows, that correctly shows the following: • Normal stress in the y-direction (o,) is positive • Normal stress in the x-direction (0.) is negative • Shear stress (Ty) is negative 3. A circular steel bar is subjected to an axial compressive load of 175 kN. The bar has a diameter of 55mm. Calculate the maximum normal and shearing stresses in the bar in Mpa. 4. A square prismatic bar with cross section dimensions a = b = 76.2 mm is subjected to an axial tensile load of P = 200 kN, as seen below. Determine the normal and shearing stresses on all faces of an element oriented using W = 35° as seen below. Units of stress should be MPa. cross section
