Cheat Sheet
- Torque definition (τ = r × F) -
Torque τ is defined as the vector cross-product between the position vector r and force F, with magnitude τ = r F sinθ where θ is the angle between them. Use the right-hand rule - point your fingers in direction of r, curl toward F, and your thumb shows the torque direction. Mastering this formula is essential for acing physics torque questions in rotational mechanics quizzes.
- Lever arm and perpendicular distance -
The lever arm r⊥ is the perpendicular distance from the pivot to the force line of action, giving τ = r⊥ F. A quick mnemonic is "pUSH Perp twists perfect," emphasizing the perpendicular component. This lever arm concept often appears in torque questions physics problems involving wrenches and seesaws.
- Static equilibrium and net torque -
For an object in static equilibrium, ∑τ = 0 and ∑F = 0, meaning all clockwise and counterclockwise torques balance. Apply this to see-saws or balanced beams, ensuring torque sums cancel for rotational stability. Many torque quiz physics items test this equilibrium condition in real-world settings.
- Rotational dynamics (τ = I α) -
Newton's second law for rotation states τnet = I α, where I is the moment of inertia and α the angular acceleration. Different shapes have known I formulas - like I = ½ m R² for a solid disk - so select the right one. This relation is central to understanding torque physics in dynamic systems.
- Real-world applications and units -
Torque is central in engines (measured in newton-metres) and biomechanics (joint torques), so practice converting units from N·m to real scenarios. Remember the SI unit for torque is the newton-metre (N·m), distinct from energy's joule despite sharing dimensions. Real-world basic torque questions often ask for unit checks and application examples.
