    Help calculating power required to drive shaft

    30 kg - 215kg = -185kg or 185 kg Multiplying this x 9.81 to get force = 1815N I am unsure what you mean here. What I did was make an integral for the Force with repsect to distance: ∫_0^xm▒( F)(x)dx =1815 [x^2/2]_0^(.6) =326.7 N "Add the amount of work it takes to get the block...
