1 Rotational motion
"Two meshing gears transmit rotational motion."
Another way of looking at this is to say that only the smaller cog is powered but it depends on which cog is to do the work.
2 Moment
- In physics, moment of force (often just moment) is a measure of its tendency to cause a body to rotate about a specific point or axis. source
- The units of torque are force multiplied by distance.
3 Mechanical advantage
- Mechanical advantage ... is the factor by which a machine multiplies force.
- The mechanical advantage of a machine can be used to find out how well a machine works and whether it can perform a particular job. source
4 Pulling power
- In simple terms, the definition of torque is the engine's rotational force.
- It differs from horsepower as it refers to the amount of work an engine can exert, while horsepower defines how quickly that work can be delivered.
- It's why torque is often referred to in layman's terms as 'pulling power', 'oomph', or 'grunt'. source
5 Power from a car's engine
- Torque is a crucial part of generating power from a car's engine, as it represents the load an engine can handle to generate a certain amount of power to rotate the engine on its axis.
- The force is measured in pounds (lb) per foot (ft) of rotation around one point.
6 Horsepower
- Torque multiplied by rpm (revs per minute) returns horsepower.
- Basically, the faster the crankshaft spins with the same amount of force, the more power an engine will make.
- A car with more hp than torque will always be quicker since this gives a car acceleration and speed.
