Torque is calculated as force times distance from the fulcrum: 10 𝑁 × 2 𝑚 = 20 𝑁 𝑚 0N×2m=20Nm.
Adding more pulleys reduces the effort needed to lift a load by distributing the weight more evenly.
A block and tackle system decreases the force needed by distributing the load over multiple pulleys.
A hydraulic press uses fluid pressure to lift or compress heavy objects.
Bevel gears are designed to change the direction of a drive by 90 degrees.
Gear A will rotate twice for every rotation of gear B because it has half the number of teeth.
A lever amplifies an input force to lift or move a heavier load.
A caliper is designed to measure the diameter of cylindrical objects accurately
A screw is essentially an inclined plane wrapped around a cylinder.
A flywheel is used to maintain a constant speed of rotation by storing rotational energy.
The mechanical advantage is the ratio of the wheel radius to the axle radius: 0.5 𝑚 / 0.1 m = 5 0.5 m / 0.1 m = 5.
