Consider the following figure. h B III (a) Determine the maximum tensile stress o, and maximum compressive stress o, (in MPa) due to the load P acting on the simple beam AB. Data are P = 6.8 kN, L = 3.4 m, d = 1.03 m, b = 80 mm, t = 25 mm, h = 120 mm, and h, = 90 mm. (Use the deformation sign convention.) o, = MPa O. = MPa (b) Find the value of d (in m) for which tensile and compressive stresses are the largest. What are these stresses (in MPa)? (Use the deformation sign convention.) d = m MPa MPа

Solid Mechanics

Engineering mechanics is a branch of science that deals with forces causing bulk motion in bodies and the effect that these forces cause on the bodies. Engineering mechanics does not deal with the internal changes that occur on account of these external forces. The internal effects in a body or a material under the action of external forces are studied in a new branch of science called solid mechanics, the strength of materials, or the mechanical behavior of engineering materials.
