A standard man (m = 70 kg) is holding a 300 g marble in his hand. The values for the masses of the hand, forearm, and upper arm, expressed as the percentage of full body mass, are as follow: hand 0.65%, forearm 1.87%, and upper arm 3.25%. Each segment's weight acts as if the mass is concentrated in the centre of mass of a segment. The points at which the weight of each segment is acting are shown in Fig. 5.1. Calculate the centre of mass of the arm.
