An engineering intern builds an rlc series circuit which includes an ac source that operates at a fixed frequency and voltage. at the operating frequency, the resistance r is equal to the inductive reactance xl. the intern notices that when the plate separation of the parallel-plate capacitor is reduced to one-half its original value, the current in the circuit doubles. determine the initial capacitive reactance in terms of the resistance r.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

On a average work day more than work place firs are reorted

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
