A steel rod with a 1.00-in. gage length and a 0.140-in. diameter is loaded in tension. At the proportional limit, a load of 1,200 lb elongates the gage length by 0.00276 in. and reduces the diameter by 0.0001 in. Determine the Poisson’s ratio.
Read DetailsAn aluminum bar with a 2.00-in. gage length, 0.235-in. width, and 0.085-in. thickness is loaded in tension. At the proportional limit, a load of 1,100 lb elongates the gage length by 0.00914 in. and reduces the width by 0.00027 in. Determine the Poisson’s ratio.
Read DetailsA steel [E = 200 GPa; ν = 0.3; α = 11 ×10-6/°C] plate has a rectangular hole at its center and four circular holes at the corners. At an initial temperature of Ti = –23°C, the plate is 80 mm wide, 115 mm long, and 16 mm thick. The rectangular hole is 25 mm wide and 65 mm long. The circular holes have a diameter of 17 mm. At a final temperature of Tf = 45°C, determine the thickness of the plate.
Read DetailsA Great Value can weighs 1.02 lb and is 2.93 in. in diameter. A Libby’s can weighs 1.07 lb and is 2.95 in. in diameter. What is the largest bearing stress that occurs between the cans and the table? Assume each can has a smooth base and sits flat on the table.
Read DetailsA load of P = 750 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,700 ksi; ν = 0.34] and has a circular cross section with a diameter of 1.16 in. Determine the magnitude of the normal strain in bar (1). Let a = 29 in., b = 16 in., and c = 10 in.
Read DetailsA load of P = 425 lb is applied to beam ABC. Bar (1) is made of aluminum [E = 10,700 ksi; ν = 0.34] and has a circular cross section with a diameter of 0.82 in. Determine the magnitude of the normal strain in bar (1). Let a = 29 in., b = 13 in., and c = 8 in.
