Problems Maximum Points Points Scored 1 8 2 10 3 12 Total 30 NAME: 1. A Tbeam shown in the figure is made of a material with tensile proportional limit of 3000 psi and a compressive proportional limit of 6000 psi. If these stresses are not to be exceeded, find the magnitude of the largest force F which may be applied to this beam in (a) downward direction (b) upward direction. Consider only the bending stresses obtained from the flexure formula. For the given Tsection the neutral axis (na) is 5.5 in. from the bottom and I = 97 in 4 about the n.a. 2. A box beam is fabricated by nailing plywood sides to two longitudinal wooden pieces, as shown in the figure. If the vertical shear at a section is V = 12 kN, determine: (a)...
