Torque vs Applied Force
Formula
Torque (Moment of Force)
Torque measures the tendency of a force to cause rotation about an axis.
Formula
tau = F * r * sin(theta)
Maximum torque occurs when the force is perpendicular to the lever arm (theta = 90 degrees).
Exemplo Resolvido
A 50 N force is applied perpendicular to a 0.3 m wrench.
- 01tau = F * r * sin(theta)
- 02tau = 50 * 0.3 * sin(90°)
- 03tau = 50 * 0.3 * 1
- 04tau = 15 N·m
Perguntas Frequentes
What is the unit of torque?
In SI, torque is measured in newton-meters (N·m). Although dimensionally identical to joules, torque is not energy.
When is torque maximized?
Torque is maximized when the force is applied perpendicular to the lever arm (theta = 90°), because sin(90°) = 1.
How does torque relate to angular acceleration?
By Newton's second law for rotation: tau = I * alpha, where I is moment of inertia and alpha is angular acceleration.
