Torque - Work done and Power Transmitted

Calculate work done and power transmitted by a constant torque. Includes calculations for angular motion, power transmission, and required torque to produce power.

Work Done

Work done in angular motion is calculated as:

W = T × θ

Where:

  • W = work done (Nm or J)
  • T = torque (Nm)
  • θ = angle (radians)

Work Done-- Nm

Power Transmitted

Power transmitted can be calculated from torque and rotational speed:

P = 0.105 × n_rpm × T

Where:

  • P = power (Watts)
  • n_rpm = speed (rev/min, rpm)
  • T = torque (Nm)

Power Transmitted-- W
Power Transmitted-- kW

Required Torque to Produce Power

To find the torque required to produce a given power:

T = P / (2π × n)

Or using rpm directly:

T = P / (0.105 × n_rpm)

Where:

  • T = torque (Nm)
  • P = power (Watts)
  • n_rpm = speed (rev/min, rpm)
