Inverse Dynamics$/$Equilibrium The image given shows the segmented hand and forearm of an individual catching a baseball. In a previous analysis someone calculated the net joint reaction force and net joint moment acting on the hand at the wrist. Use this information to move up the kinetic chain and calculate the net joint reaction force and net joint torque actinfon the forearm at the elbow.

The vectors for the wrist joint reaction force and joint moment acting ON THE HAND at the wrist are given as:

$R_{{?}_{?}}(WH)=350x_{-}200y(N)$

$M_{{?}_{?}}(WH)=20z_{{?}_{?}}(N^{**}(m))$

The acceleration vectors of the forearm segment are given below:

$a_{{?}_{?}}(F)=-15x_{-}30y(\frac{m}{s^2})$

$a_{{?}_{?}}(F)=600z_{ra\frac{d}{s^2}}$

Inertial and Anthropometric Characteristics of the Forearm

mass of the forearm $m=1\mathrm{.}5kg$

length of forearm $L=0\mathrm{.}3m$

moment of inertia about the elbow joint center $I=0\mathrm{.}035k{g}^{**}{m}^2$
