It is the moveable pulley only, which gives any mechanical advantage.
This is therefore the mechanical advantage of the wheel and axle.
What mechanical advantage in number of revolutions does it give?
Wheel and Axle and Pulley; common applications, mechanical advantage.
The mechanical advantage can be worked out mathematically,—a good problem for the physics or mathematics class.
It has the start of all other languages—the mechanical advantage—the position.
Hence the mechanical advantage of a lever is easily found by finding the ratio of the effort arm to the weight arm.
In a similar way, the mechanical advantage of any machine is found by finding the ratio of the resistance or weight to the effort.
By shifting the bolt into the centre nearest the pump-rod, the mechanical advantage of the workman may be doubled.
It seems a mechanical advantage, and great benefit it is to each speaker, as he can now paint out his thought to himself.
|mechanical advantage |
The ratio of the output force (acting on a load) produced by a machine to the applied effort (the input force). See also efficiency.
