About Work Done by Torque Calculator (Formula)
The Work Done by Torque Calculator is an essential tool for engineers and mechanics involved in analyzing rotational motion. Torque is a measure of the force that can cause an object to rotate about an axis. Understanding how much work is done by this torque is crucial in various applications, from automotive engineering to machinery design. This article will explain the formula used in the Work Done by Torque Calculator, guide you on how to use it, provide a practical example, and address frequently asked questions.
Formula
The formula for calculating the work done by torque is:
Wt = t * d(θ)
Where:
- Wt represents the work done by torque.
- t is the torque applied (in Newton-meters).
- d(θ) is the change in angular displacement (in radians).
How to Use
- Determine the Torque (t): Measure the torque applied in the system, typically in Newton-meters (N·m).
- Measure Angular Displacement (d(θ)): Determine the change in angular displacement, expressed in radians. You may need to convert degrees to radians if necessary (1 radian = 180/π degrees).
- Input Values into the Formula: Substitute the values of torque (t) and angular displacement (d(θ)) into the formula: Wt = t * d(θ).
- Calculate the Work Done: Perform the calculation to find the work done by the torque.
Example
Let’s calculate the work done by torque for a system with the following parameters:
- Torque (t): 15 N·m
- Change in Angular Displacement (d(θ)): 2 radians
Using the formula:
Wt = t * d(θ)
Wt = 15 N·m * 2 radians
Wt = 30 Joules (J)
This result indicates that the work done by the torque in this scenario is 30 Joules.
