The gear train transmits power from a motor to a machine at E. The motor turns at 2750 rpm. The diameter of solid shaft (1) is 1.53 in., the diameter of solid shaft (2) is 1.9 in., and the allowable shear stress for each shaft is 4.4 ksi. Assume NA = 20 teeth, NB=92 teeth, NC=38 teeth, ND=59 teeth. Determine: (a) the maximum power P that can be transmitted by the gear train. (b) the torque TE provided at gear E. (c) the rotation speed omega of gear E.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
