here's the question as written: A person is attempting to pull a large stone wheel up a step. The wheel has a mass of 300kg. Assuming the force the person applies is horizontal and at the certer of gravity, what imust the force be to start the wheel rolling over the curb? alright, so i found the weight of the wheel, 2940N, the pivot poing is going to be at the corner of the step, and the angle created between where the wheel hits the ground and the pivot point to be 16.7degrees. i have no clue as to what direction to go in next, can anyone help?
