For a brass alloy, the following engineering stresses produce the corresponding plastic engineering strains prior to necking: Engineering Stress (MPa) Engineering Strain
315 0.105
340 0.220
On the basis of this information, compute the corresponding true stresses and true strains.

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false

Aplate clutch has a single pair of mating friction surfaces 250-mm od by 175-mm id. the mean value of the coefficient of friction is 0.30, and the actuating force is 4 kn. a) find the maximum pressure and the torque capacity using the uniform-wear model. b) find the maximum pressure and the torque capacity using the uniform-pressure model.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
