Impulse and Everyday Safety Devices
Shock absorbers and yielding surfaces reduce injury by extending the time over which motion is brought to rest.
Open article →Friction in Bicycle Motion
Static friction pushes the driven rear wheel forward and acts backward at the front wheel; kinetic friction appears only during slipping.
Open article →Banked Roads and Safe Turning
Raising a curve's outer edge creates a banking angle; the angle, radius, speed and friction determine whether a car turns safely.
Open article →Centrifugal Effects in Turns and Rotating Platforms
Passengers and loose objects seem pushed outward during turning, while friction or an inclined rotating platform helps prevent outward motion.
Open article →Force Couples and Turning
A couple has zero net force but its separated equal opposite forces produce moments in the same rotational sense.
Open article →Principle of Moments and Lever Advantage
Stationary equilibrium requires zero net force and torque; a longer effort arm lets a smaller effort balance or lift a larger load.
Open article →Centre of Gravity and Static Balance
The centre of gravity is the point through which a body's weight acts; supporting it there balances weight, reaction and torque.
Open article →Locating the Centre of Gravity
An irregular lamina's centre of gravity can be located by trial pivoting or by suspending it and using the equilibrium line.
