Part E You can enter compound units that are combinations of other units that are multiplied together. To enter the - explicitly type (shift + 8) on the keyboard, or use the template in the Templates menu. Torque can be calculated by multiplying the force (N) applied at 90 to the lever arm at a distance (m) from the pivot point (point of rotation), the compound SI unit for the torque is N·m If the force (at 90° to the lever arm) applied is 15 N and it is applied at 2.0 m from the pivot point (point of rotation), what is the torque on the lever? Express the torque with the appropriate units. View Available Hint(s) VaueUnits Submit Next >

Explanation / Answer

Torque = F * r * sin(theta)

Given theta = 90o . So sin (theta) = sin 90o = 1

r = 2.0 m and F = 15 N

Torque on the lever = 15N * 2.0 m = 30 N m
