Two diagrams showing a wrench on a bolt. Diagram 1: The wrench handle is horizontal to the right. A force vector F is applied at distance r from the pivot at a 30-degree angle above the horizontal handle. Diagram 2: The same wrench handle. A force vector F is applied at distance 2r from the pivot, pointing vertically upward, forming a 90-degree angle with the handle.
Comparison of two different force applications on a wrench handle.
A technician uses a wrench to loosen a bolt. In the first attempt, the technician applies a force of magnitude \(F\) at a distance \(r\) from the center of the bolt, such that the force makes an angle of \(30^{\circ}\) with the wrench handle. In the second attempt, the technician applies a force of the same magnitude \(F\) at a distance \(2r\) from the center of the bolt such that the force is perpendicular to the wrench handle. What is the ratio of the magnitude of the torque produced in the second attempt to the magnitude of the torque produced in the first attempt?
