When the palmaris longus muscle in the forearm is flexed, the wrist moves back and forth. If the muscle generates a force of 49.5 N and it is acting with an effective lever arm of 2.65 cm , what is the torque that the muscle produces on the wrist

Respuesta :

Answer:

1.1397 Nm

Explanation:

When the palmaris longus muscle in the forearm is flexed, the wrist moves back and forth.

If the muscle generates a force

[tex]F = 49.5 N[/tex] and [tex]r = 2.65 cm[/tex] , then the torque is equal to [tex]rF[/tex]

we see that r = 2.65 cm = 0.0265 m

therefore

torque = 0.0265 x 49.5

= 1.1397 Nm
