Physics - Torque
A particle is acted on by two torques about the origin: T1 has a magnitude of 4.3 N*m and is directed in the positive direction of the x axis, and T2 has a magnitude of 3.2 N*m and is directed in the negative direction of the y axis. What are the magnitude [in N*m] and ...

When we studied the concept of work, we learned that work = force x distance. Now we learn that torque = force x distance. What's different about these two definitions?A) For work, distance and force are in the same direction; for torque they are perpendicular to each other.B...
