1. The problem statement, all variables and given/known data A transfer car moves concrete slabs. Given values are wheel diameter D, shaft diameter d, rolling resistance FL , speed v, car weight mv , load weight mk , output power P at rotation speed n, average torque Mm , motor moment of inertia Jm , fan moment of inertia Jt and efficiency of the mechanical transmission system η. a) Calculate start-up acceleration and distance (up to maximum speed). b) Calculate the torque of the driving shaft of the gear at start. 2. Relevant equations None given... (this is the main problem). I am studying a course abroad which has support material in a foreign language. I have found these so far: P=Mm⋅ω a=R⋅α α=dω/dt 3. The attempt at a solution I have tried to find the angular acceleration using power, torque, radius and speed, however, these don't work in the start-up case since v=0. As for torque, I think I first need to find the acceleration and the just input into torque=moment of inertia⋅angular acceleration I also don't know how and what forces to sum to calculate the torque.
