Choosing an appropriate Metric ISO 2904 Power Screw given the maximum load

Hi, So I have a uni project and were required to design a jockey wheel and corresponding power screw. We're given a maximum load and have to do the relevant calculations, moment of torque, efficiency etc. My question is I don't understand how to take the given maximum load and find the relevant screw diameter and dimensions, the screw we have to use must be a Metric Trapezoidal thread ISO 2904. Any help would be much appreciated.
