Acylindrical rod with length l bridges two thermal reservoir $ and %. at the steady state condition, temperature is observed to be only function . the outer surface of the rod is perfectly insulated, and volumetric heat generation is negligible. if material property , linearly changes with position x, (e. g. = + , where a and b are constant and known),

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
