Abrass alloy is known to have a yield strength of 275 mpa (40,000 psi), a tensile strength of 380 mpa (55,000 psi), and an elastic modulus of 103 gpa (15.0×106 psi). a cylindrical specimen of this alloy 6.4 mm (0.25 in.) in diameter and 217 mm (8.55 in.) long is stressed in tension and found to elongate 5.0 mm (0.20 on the basis of the information given, is it possible to compute the magnitude of the load that is necessary to produce this change in length? if not, explain why.

Abrake has a normal braking torque of 2.8 kip in and heat-dissipating cast-iron surfaces whose mass is 40 lbm. suppose a load is brought to rest in 8.0 s from an initial angular speed of 1600 rev/min using the normal braking torque; estimate the temperature rise of the heat dissipating surfaces.
