  1. I have a question as i’m struggling with calculating this problem, I have an input force of 600N the Input force is 12 times greater than the Load distance and the MA is 1/2 that of the VR I have to calculate the VR and the Load distance.

    So my given data is P=600N, MA = 1/2VR and Pd = 12Ld. I don’t know where to start. could you give me some advice on the matter?
