The Wheel: Torque Torque is the measure of how much a force acting on an object causes it to rotate. The object usually rotates about an axis on a pivot point. The distance from the pivot point is called the moment arm. We can use the distance from the pivot point, the force, and the sin of the angle to calculate the torque. Torque = r x F = r F sin(theta) Torque comes into play when we use the crank shaft for each Dat Boi. We can use the the torque formula to find out, which crank shaft we would want if we are looking for a target torque.   Say we have a crank shafts that are 0.5 meter long (Unicycle One) and 0.75 meter long (Unicycle Two), both unicycles are under the same force of 100 newtons, and have an angle of 30 degrees. (Unicycle left)                                        (Unicycle right) Torque = r x F = r x F x sin(theta)           Torque = r x F = r x F x sin(theta) Torque = 0.5 x 100 x sin(30)                   Torque = 0.75 x 100 x sin(30)     Torque = 25 Nm                                       Torque =  37.5 Nm Based on the data from the two crankshafts we would choose the 0.75 meter crankshaft if we wanted to get greater torque and 0.5 meter crankshaft if we wanted a lower torque. Based on the data the greater the radial distance the more torque we will recieve from the crank shaft.
