Moment of Force Formula:
From: | To: |
Definition: This calculator determines the torque (moment of force) produced when a force acts at an angle to a lever arm.
Purpose: It helps engineers, physicists, and students analyze rotational systems where forces aren't applied perpendicularly.
The calculator uses the formula:
Where:
Explanation: The sine function accounts for the angular component of the force that contributes to rotation.
Details: Accurate torque calculations are essential for designing mechanical systems, analyzing rotational equilibrium, and understanding rotational dynamics.
Tips: Enter the force magnitude, distance from pivot point, and angle between force and lever arm. Angle must be between 0° and 90°.
Q1: What happens at 0° and 90° angles?
A: At 0° (parallel), torque is 0. At 90° (perpendicular), torque is maximum (F × r).
Q2: Why use sine instead of cosine?
A: We use sine because torque depends on the perpendicular component of force to the lever arm.
Q3: What units should I use?
A: Force in Newtons (N), distance in meters (m), angle in degrees (°). Result is in N m.
Q4: Does this work for 3D systems?
A: This is for 2D systems. 3D systems require vector cross products for full analysis.
Q5: How does angle affect torque?
A: Torque increases from 0° to 90°, reaching maximum at perpendicular application.
