Elevator Mechanics Exam 300 Questions

and Answers 100% Solved


What's the equation for the volume of the cylinder? - ✔✔V (volume)= pi

multiplied by R squared multiplied by the height

Example: radius is 6" height is 30

V=3.1416•6•6•30

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

You find the power(watts)? - ✔✔P=I squared (amps) multipled by

R(resistance)

Example:P=4.5•4.5•16.0

4.5•4.5=20.25

20.25•16.0=324

P=324

What is the equation for distance? - ✔✔D=R•T

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

What is the equation for pressure? - ✔✔pressure = force/area

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

,©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
What is the equation For voltage? - ✔✔E=I•R

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

What is the equation for current or amps (i)? - ✔✔I=E/R

i (current in Amps)

R=(resistance in ohms)

E(volts)

What is the equation for series voltage? - ✔✔Et=E1=E2=E3

ET(total voltage)

What is the equation for series resistance? - ✔✔Rt=R1+R2+R3

R=resistance

What is the equation for series current? - ✔✔It=i1=i2=i3

it=total current in amps

I=current in amps

How do you calculate resistance of a wire? - ✔✔R=P•L/A

R=resistance of the wire

P= resistivity constant of the wire

L=length of the wire

A=cross sectional area of the wire

What is the equation for parallel voltage? - ✔✔Et=E1=E2=E3

, ©JOSHCLAY 2024/2025. YEAR PUBLISHED 2024.
E=voltage

ET=total voltage

What is the equation for parallel current? - ✔✔iT=i1+i2+i3

I=current in amps

iT=total current in amps

What is the equation for parallel resistance? - ✔✔RT= 1 divided by 1/R1 +

1/R2 +1/R3

Add each fraction (1/R1-1/R3)

Divide the answer of each resistance by 1

****

What is the equation for pulley relationship? - ✔✔(Diameter of First pulley)

•(RPM of first pulley) (diameter of second pulley) •(RPM of second pulley)



Take RPM of the first pulley and multiply it by the diameter of the first

pulley, then divide that by the diameter of the second pulley.

What is the equation for sprocket relationship ? - ✔✔(Number of teeth in

sprocket1)•(RPM of sprocket 1)= (number of teeth in sprocket 2)•(RPM of

sprocket 2)
