A wrench 1 ft long lies along the positive x-axis and grips a bolt located at the origin. If a force of 5 lbs is applied parallel to the y-axis (perpendicular to the wrench) in the upward direction, find the magnitude of torque on the bolt.

Solution

Here force applied = 5 lbs

Distance from bolt = 1 ft

Hence torque on the bolt = force x distant

= 5 lb ft.
