Torque

Last week Friday in class we learned about torque. Torque is a measure of angular acceleration and the change in angular velocity. Using the formula T=rf someone could find the torque that a center object has when it is rotated. In this equation t is the torque, r is the distance from axis to force and f is the force exerted. Torque can be found everywhere in life including in this picture of an engine. This engine is part of my dads "project" to build a quarter mile race car and it depends largely on torque in order to go fast. The unit for torque is Newton-meters but pound-feet in America. In the torque of a car, the engine is the source of the force exerted and the axis of rotation is the turning crankshaft which cannot be seen in the photo because it is underneath the engine. Torque in cars is slightly different from regular torque in everyday life because the location of the force and axis of rotation are in different locations. But the concept is still the same in that there is some force exerted which causes an object to rotate therefore creating torque.
