Today in class, we learned a new type of force, one that is rotational called torque. Torque is force in a rotational direction and has an equation of: t = rf, where t is the torque, r is the distance from the axis to the force, and f is the force. A wrench is a perfect example, as you use your hands to turn the bolt to release or tighten, creating torque. And when using a wrench, the farther out you place your grip, the easier it is to turn, since r is increased creating more torque to open up the bolt. This is why some construction workers use extra tubes to connect to the small tools to make their life easier. Though they may not know how it exactly helps, we do! Definition of torque according to Kinetic Books: A force that causes or opposes rotation!

ha the "magic" wrench.... it's not magic, it's physics!
If it doesn't work, its physics!
Don't you think it would be tight if someone could make like a 1000 foot wrench that would allow me to like knock over something the size of an office building with a small tug.
