The torque of a Lazy Susan describes its tendency to turn, measured in Newton meters.
A Lazy Susan is a circular platform that rotates about a pivot. The device is common in restaurants, particularly Chinese restaurants where several people share multiple dishes. It moves dishes around a table easily. The torque of a Lazy Susan describes its tendency to turn, measured in Newton meters. This value is related to the size of the device, the size of the force turning it and the angle at which the force acts.
Instructions
1. Find the sine of the angle between the force turning the Lazy Susan and the wheel's radius. For example, if the force is completely perpendicular, the angle is 90 degrees: sin (90) = 1.
2. Multiply this answer by the size of the force. For example, if a force of 200 Newtons turns the Lazy Susan, then 200 --- 1 = 200 Newtons.
3. Multiply this adjusted force by the wheel's radius. For example, if the radius is 0.15 meters, then 200 --- 0.15 = 60 Newtons. This is the Lazy Susan's torque, measured in Newton-meters.
