## Homework Statement

Need to find input torque, output torque and input torque (omega) all NM

Data i have is

Input RPM = 9700

Output RPM = 1950

GEAR 1 = 12, 2 = 40, 3=30, 4=20 (Radius) with module 2 (x 2 for diameter)

Power = 2.3Kw

## Homework Equations

Turn power to H.P giving 3.083 H.P

Use

(63025 * H.P) / R.P.M = T

T = 20.1Nm

Ang Velocity

V(omega)input = R.P.M in * 2pi/60 = rad/s

V(omega)output = R.P.M out * 2pi/60 = rad/s

Input Rad Torque

T(omega) in = V(omega)in * Torque

## The Attempt at a Solution

I would say the torque is 20.1Nm

I am getting confused with these torques,

Situation is a 2 stage gearbox, and torques need to be found, including angular torque, but can't seem to find the formulas i really need.

Pretty simple i am sure, but its not clicking for me right now.
