The brass shell (ab 5 11.6 3 1026/8f) is fully bonded to the steel core (as 5 6.5 3 1026/8f). determine the largest allowable increase in temperature if the stress in the steel core is not to exceed 8 ksi.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
