Question

D. 2 14. When changing the insertion points from position A to C (below) the amount of muscle force needed to lift the Note-there are two ways to determine this. c. stays the same weight a. increases b. decreases 15. When changing the origin points from position D to F (to the right) the amount of muscle force needed to lift the weight . (two ways to determine) c.stays the same a. Increases b. decreases FM CB A e third, feree FM 17. Given the two muscles below where the force in the muscle is equal in both: More joint torque is produced in A, but more joint stabilization in B. More joint torque is produced in B, but more joint stabilization in A. More joint torque and stabilization in A. More joint torque and stabilization in B. None of the above a. b. c. d. e.

Explanation / Answer

14) option b :decreases(as distance decrease)
f=m*a=m*d/t

15)option b :increases(as distance increases)
f=m*a=m*d/t

17) option :b
More joint torgue is produced in B, but more joint stabilization in A
torque can be written as T = F * r * sin(theta)
