How much does a human arm weigh?

In: Weight and Mass [Edit categories]

Answer:

The total arm mass is given as mean 3.216kg with a standard deviation of 0.464kg
in Clauser, "Weigth, volume, and center of mass of segments of the human body", 1969, p.45
(http://www.ulb.ac.be/medecine/anatemb/biblio/Clauser1969.pdf):

More details in Chandler, "Investigation of Inertial Properties of the Human Body", 1975, p.72-79
(http://www.ulb.ac.be/medecine/anatemb/biblio/Chandler1975.pdf)
come the following data:
Upper arm (right): mean 1.843kg s.d. 0.218kg.
Upper arm (left): mean 1.888kg s.d. 0.299 kg.
Forearm (right): mean 1.113kg, s.d. 0.271kg.
Forearm (left): mean 1.088kg s.d. 0.185kg
Hand (right): mean 0.400kg s.d. 0.091kg
Hand (left): mean 0.374kg s.d. 0.062kg
That gives a total mean arm mass of 3.35kg (for right and left).
