If the weight in a wheelbarrow is 400 lbs and is 15 inches from the center of the wheel, and the handles are 60 inches from the center of the wheel, how much force is required to lift the wheelbarrow?

Question

To analyze the wheelbarrow problem, we need to consider torque about the wheel's center to determine the lifting force required.
First, identify the torque produced by the weight: the weight is 400 lb and acts 15 inches from the center, so the torque is 400 × 15 = 6000 in-lb in the clockwise direction.
Next, identify the torque produced by the lifting force at the handles: the handles are 60 inches from the center, so the torque due to the lifting force F is F × 60 in-lb in the counterclockwise direction.
For the wheelbarrow to just lift (steady equilibrium before lifting off), these torques must balance, so F × 60 = 6000.
Solve for F: F = 6000 / 60 = 100 lb.
Hence, the force required to lift the wheelbarrow is 100 pounds, assuming negligible friction and that the weight distribution and geometry align with the given lever arms. If any values or units were inconsistent, you would need to convert consistently, but here inches and pounds are already aligned with the torque relation.
