Question
Analyze the biomechanics of doing a finger push-up. Determine the effect of finger push-ups on the finger muscles and joints. The figure below shows the forces acting on a single finger during a finger push-up. Assume that the weight of the finger is negligible. If 0 FN lf length of finger 8: angle the finger makes with the horizontal Fm: magnitude of the finger flexor muscles lm: distance away from the finger joint to the finger flexor muscles Om: angle with respect to length of finger FN = 80 N = 6 cm = 50° От Compute Fm and the joint reaction forces (Jx & Jy) at the thumb given these parameters: If Om = 0.75 cm = 30° Fm
