Hi everyone. I'm trying to work out what size shock absorber to use. It's going under a seat so just the weight of a man really that it has to support. I've found a website showing the equations I need but I'm not sure about one of the steps. In step 2 it asks force output of the motor/drive. For my problem would this just be the weight x 9.81?
