Question

In this activity, we will learn how to apply the equation for torque. We will use the equation to calculate the torque when different forces are applied to a torque wrench. This equation tells us to multiply the magnitude of vecr by the magnitude of the perpendicular component of vecf to get the magnitude of vec tau. What is the equation for torque?

1) vec tau = vecr * vecf
2) vec tau = vecr / vecf
3) vec tau = vecr + vecf
4) vec tau = vecr - vecf

Answer 1

The equation for torque is τ = rF sin θ.

Step-by-step explanation:

The equation for torque is: τ = rF sin θ. In this equation, τ represents torque, r represents the distance from the pivot point to the point where the force is applied, F represents the magnitude of the force, and θ represents the angle between the force and the vector directed from the point of application to the pivot point.
