A load of P = 380 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 1.05 in. If the normal stress in bar (1) is limited to 12 ksi, determine the factor of safety for bar (1). Let a = 35 in., b = 15 in., and c = 8 in.

A short column is composed of two steel [E = 30,000 ksi, ν = 0.30] segments, each with a length of 5.6 in. Segment (1) is hollow with an outside diameter of 1.20 in. and a wall thickness of 0.15 in. Segment (2) is hollow with an outside diameter of 1.50 in. and a wall thickness of 0.15 in. How much shorter does the column become after a load of P = 710 lb is applied?

A short column is composed of two steel [E = 31,000 ksi, ν = 0.29] segments, each with a length of 5.7 in. Segment (1) is hollow with an outside diameter of 1.30 in. and a wall thickness of 0.14 in. Segment (2) is hollow with an outside diameter of 1.58 in. and a wall thickness of 0.14 in. How much shorter does the column become after a load of P = 670 lb is applied?

A load of P = 320 lb is applied to beam ABC. Bar (1) has a square cross section with a width of 0.95 in. If the normal stress in bar (1) is limited to 14 ksi, determine the factor of safety for bar (1). Let a = 29 in., b = 14 in., and c = 8 in.
