A given load is driven by a 2300 V eight-pole 500 hp three-phase synchronous motor with the following load and motor data. Determine the current IA that is necessary for this operating condition. Load: TL = 0.4 * w Nm and
TRL = 0.6 * W Nm Motor:
Ef = 2000
V; Xa = 5.12

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
