 In a tensile test of an aluminum rod it has a calibrated length of 50.8 mm and a diameter of
12.74 mm. A load of 3 180 kg and an elongation at the elastic limit of 0.0175 cm was recorded. The distance in the areacalibrated after the break is 5.65 cm and the final diameter in the section of the fracture was 1.05 cm. In a tensile test of an aluminum rod it has a calibrated length of 50.8 mm and a diameter of 12.74 mm. A load of 3 180 kg and an elongation at the elastic limit of 0.0175 cm was recorded.

A long, uniform rod of length 0.500 mm and is rotating in a circle on a frictionless table. The axis of rotation is perpendicular to the length of the rod at one end and is stationary. The rod has an angular velocity of 0.42 rad/srad/s and a moment of inertia about the axis of 3.20×10−3 kg⋅m2kg⋅m2 . An insect initially standing on the rod at the axis of rotation decides to walk to the other end of the rod. When the...

A 50 cm long rod is half aluminum and half copper. The aluminum end is in boiling water. The end of an aluminum rod (50 cm long) is maintained at 100 C by immersing in a pot of boiling water and the other end at 00C by an ice-water mixture. If the cross-sectional area of the rod is 1.3 cm2, how much will the rod melt in 20 min? What will be the steady temperature at the Al-Cu junction?
