During lab activity 3 (Planar Motion) we used a two-segment model to analyze arm reaching. Using your own body dimensions and the anthropometric proportions given, calculate each body segment parameter (upper arm and forearm) as described below.

Segments

Inertial Properties

Arm Segments

Upper Arm (UA)

Forearm (FA)

Length

0.186 (body height)

0.148 (body height)

Mass

3.12 % (body mass)

1.73 % (body mass)

CoM location

44.5% UA (length)

43.4% FA (length)

Moment of Inertia (I)

IUA = mUA * (CoMUA)2

IFA = mFA * (CoMFA)2
