Analysis of the forces exerted by the radial muscles described so far
In chapters X and XII we considered the apparent forces exerted by several muscles, the flexor and extensor muscles of the carpus and of the second and third phalanges, the deltoid and the glutei, assuming that these muscles were made of bundles of parallel fibres and pulled their tendon and the resistance thus attached in a direction parallel to the length of these fibres. This is not exactly true since these muscles are made of radial fibres. Therefore, the forces which they exert must be determined more accurately. It will apppear that their contraction requires a greater effort.
