$$IMA = \fracd_ind_out = \fracd_ed_r$$ (Where $d_e$ is effort distance and $d_r$ is resistance distance) Note: For specific machines, IMA may be calculated differently (e.g., for a lever: length of effort arm / length of resistance arm).
A:
A lever has an input arm (effort arm) length of 2 meters and an output arm (resistance arm) length of 0.5 meters. Find the IMA. $$IMA = \fracd_ind_out = \fracd_ed_r$$ (Where $d_e$ is
