In a rolling operation of a 8 inch thick aluminum plate (average fow stress nch andhe inch using a rolling mill with a maximum power of 2000 hp at 100 rpm. roll radius is 4 plate width is 6 inch. assume a coefficient of friction of 0.5. (1hp 33000 lb. ftlmin) 15 kpsi) to a 3 0 rpm. roll radius is 4 inch and the a. b. c. what is the maximum draft that you can achieve? what is the total power required to achieve the maximum draft per pass? what is the required number of passes?

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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.

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.
