. Using an adder, draw a circuit to increment or decrement an unsigned 6 PT 4-bit number, X = {X3 X2 X1 X0}. Let X connect to the adder A inputs and let the result be N = {N3 N2 N1 N0}. Ignore the carry-out. Let ID be the increment or decrement signal (0 = increment, 1 = decrement). Hint: Do not use the carry-in input.

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
