Herz explained in his patent how his cam would achieve this:  . . . in working with such apparatuses, during the whole movement, th muscles shall be exerted in accordance with their momentary tension or pulling force. This meant there would be no sticking points so the muscles would be working hard throughout the entire lift.<BR>A strength curve is a mathematical model that represenU)T]lt*iZ}Z9cv\^"FX9;F1[ Tlض%9TWI)BiiȚ1> &@q\P';?+XTJ>aA" 8:lВUG!X0M UpFG>`ĎOg1\Nޜ3jtFI:i[R[kqwJdx<]zba3ǘy3@+V}tOźQ(BKQFSNǹ[\t-7s֝5(Y{y#7X C=XW}`5r<Hs\Ν;C$#36:Ÿ[h&K/=[.cӏjA$H@b ^isn&('
