Name: _____________________________ Section: __________ Problem #1 (35 points): A steel beam 12 ft long is simply-supported at its ends and carries a uniformly distributed load of 1 kip/ft over its entire length. The beam has a T-shaped cross section with the neutral axis 2.625 in below the top surface, as shown below. Determine: (a) The largest shear force and bending moment in the beam. (b) The maximum shear stress on the cross section. (c) The maximum normal stress on the cross section. 8 in 6 in 2 in 2.625 in N.A. 1.5 in 12 ft 1 kip/ft

Name: _____________________________ Section: __________ Problem #2 (35 points): A structural steel cantilever beam 6 ft long supports a concentrated load of 5 kips at the free end. The beam has an I-shaped cross section, as shown below. Determine: 1 in 8 in 8 in 1 in 1 in (a) The largest shear force and bending moment in the beam. (b) The maximum shear stress on the cross section. (c) The maximum normal stress on the cross section. 5 kips 6 ft
Name: _____________________________ Section: __________ Problem #3 (15 points): The T beam shown below is made of a hardened plastic material. The location of the neutral axis and I z are given in the figure. The allowable normal and shear stresses in the material are σ allowable = 2,688.3 kPa and τ allowable = 82.4 kPa. Determine: (a) The largest bending moment that can be applied about the z-axis (i.e. neutral axis). (b) The largest permissible vertical shear force. 80 mm 34 mm 46 mm 20 mm 60 mm N A y z I z = 2.31 × 10 6 mm 4 = 2.31 × 10 -6 m 4 40 mm
