Elevator mechanics exam questions and

answers

What's the equation for the volume of the cylinder? Ã¢Å“â€Ã¢Å“â€V (volume)= pi multiplied by R squared

multiplied by the height

Example: radius is 6" height is 30

V=3.1416Ã¢â‚¬Â¢6Ã¢â‚¬Â¢6Ã¢â‚¬Â¢30

A drill draws a current (I) of 4.5 amps and resistance of 16.0 ohms, how do You find the

power(watts)? Ã¢Å“â€Ã¢Å“â€P=I squared (amps) multipled by R(resistance)

Example:P=4.5Ã¢â‚¬Â¢4.5Ã¢â‚¬Â¢16.0

4.5Ã¢â‚¬Â¢4.5=20.25

20.25Ã¢â‚¬Â¢16.0=324

P=324

What is the equation for distance? Ã¢Å“â€Ã¢Å“â€D=RÃ¢â‚¬Â¢T

D(distance=R(rate) multiplied by T(time)

What is the equation for pressure? Ã¢Å“â€Ã¢Å“â€pressure = force/area

P(pressure)= F(force) divided by A(area)

What is the equation For voltage? Ã¢Å“â€Ã¢Å“â€E=IÃ¢â‚¬Â¢R

voltage (E) = current(I) x resistance(R)
