✓ A small force can produce a huge turning effect
If applied far from the pivot, even a gentle push makes the body spin.
✓ Door handles are placed near the free end
Maximum distance from the hinge → maximum torque per newton of effort.
✓ Long spanners loosen tight nuts more easily
Doubling handle length halves the force needed for the same torque.
✓ Steering wheels use torque for control
A small tangential force on the rim is amplified by the radius of the wheel.
✓ Bicycle pedals & gears multiply effort
A bigger sprocket gives a larger turning effect on the rear wheel.
✓ Ancient hand flour grinders use torque
Centuries-old design — radius of the handle determines the effort required.
