A 30.0 cm wrench is used to generate a torque at a bolt. A force of 50.0 N is applied at the end of the wrench at an angle of 70.0 degrees. The torque generated at the bolt is
A) 10.4 N·m.
B) 14.1 N·m.
C) 19.7 N·m.
D) 21.5 N·m.
E) 26.2 N·m.

Question

Quizplus · Accepted Answer

To calculate the torque generated at the bolt, we use the formula:
Torque = Force x Lever Arm x Sin(θ)
where
- Force = 50.0 N
- Lever Arm = 30.0 cm = 0.3 m (since torque is calculated in SI units, we need to convert cm to m)
- θ = 70.0 degrees

Plugging in the values, we get:
Torque = 50.0 N x 0.3 m x Sin(70.0) = 14.1 N·m

Therefore, the answer is B.
