You are given the transformer pictured below. what is the voltage across the load resistor if "a" is 7, r2 is 34k ohms, r1 is 15k ohms, and v1 is 87 volts? note that r1 is large so you cannot assume that it has negligible resistance. assume that the transformer is ideal. give your answer in volts to 3 significant digits.

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
