Final answer:
The torque exerted on the bolt when a person pulls a wrench with a force of 50 N at a distance of 0.2 meters from the bolt is 10 newton-meters (N·m).
Step-by-step explanation:
The subject of this question is Physics, and it appears to be at a High School grade level. When you grip a wrench and pull it with a force of 50 N at a distance of 0.2 meters from the bolt, you are applying a torque to the bolt. Torque is calculated as the force applied multiplied by the distance from the pivot point (the center of the bolt, in this case) and the angle at which the force is applied. In this scenario, the force is perpendicular to the wrench, which means the angle is 90 degrees, and the sine of 90 degrees is 1. Therefore, the formula simplifies to just the product of the force and distance.
Using the formula, the torque (T) can be calculated as:
T = force x distance
T = 50 N x 0.2 m
T = 10 N·m
Thus, the torque exerted on the bolt is 10 newton-meters (N·m).
