Technical Physics 1 Torque

Equilibrium Concurrent forces - all forces have a common point of application S Fx = 0 S Fy = 0 Nonconcurrent forces - forces do not have a common point of application S Fx = 0 S Fy = 0 S t = 0

Torque Torque - the product of the applied force (F) and the moment arm ( r^) .
