Torque values available vary with size but range up to approximately 75,000 FT-LB. [5] Impact wrench – An air powered socket wrench that delivers high torque output by storing energy in a rotating mass, then delivering it suddenly to the output shaft. Nearly every auto body or mechanic shop will have an air compressor and impact wrench to ...

A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...
Back extension performed at an angle using an exercise ball. Back extensions can be performed with or without various equipment. Without any equipment It may be performed on the ground by lying prone with arms overhead and lifting the arms, upper torso, and legs as far as possible. Gravity provides resistance to strengthen the back extensor ...

where is back EMF, is the constant, is the flux, and is the angular velocity. By Lenz's law, a running motor generates a back-EMF proportional to the speed. Once the motor's rotational velocity is such that the back-EMF is equal to the battery voltage (also called DC line voltage), the motor reaches its limit speed.
A torque multiplier allows the user to generate high torque output without the use of an air compressor or impact gun. A torque multiplier is generally used when there are space limitations that disallow the use of long handles. They are also used as a safer alternative to a cheater bar as lever length and operator effort are both reduced.
The value in Système International (SI) units is given by multiplying the following exact factors: One pound (mass) = 0.453 592 37 kilograms [1] Standard gravity = 9.80665 m/s 2 [1] One foot = 0.3048 m [1] This gives the exact conversion factor: One pound-foot = 1.355 817 948 331 400 4 newton metres.
