2. As part of US Army Ranger training, soldiers have to push a heavily loaded cart that is missing a wheel on one side (this is a real test!). Most people just grab a hold of the side and lift. They then struggle and shuffle and push it along the path. But YOU know something about torque and want to find a way to balance the cart so that everyone only has to push it. You find a log, tie it to cart, and have one dude sit on the log. How far out on the log does your buddy have to sit to * * balance the cart? Solving for m Here are the variables: The Load is 400kg and the center of mass of the load is 0.6m from the wheel. Your buddy weighs 75kg. 400 kg = - 3924 N . lom 75 Kg Here's how this looks: 75 kg = 735.75 IN E 400 kg (Hint: There are two torques here being produced about the wheel. The torque of the load, and the torque of the person on the log. If the cart is on balance the Sum of the torques will be zero.)
