A 4-in-wide polyamide F-2 flat belt is used to connect a 3-in-diameter pulley to drive a larger pulley with an angular velocity ratio of 0.3. The center-to-center distance is 10 ft. The angular speed of the small pulley is 1500 rev/min as it delivers 3 hp. The service is such that a service factor Ks of 1.3 is appropriate. a) Find Fc, Fi, (F1)a, and F2, assuming operation at the maximum tension limit. b) Find Ha, L, and the safety factor nfs. c) Find the dip

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.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.

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
