QUESTION:
(II) Use Table to calculate the position of the
of an arm bent at a right angle. Assume that the person is
tall.
ANSWER:
Solution 55P:
We have to determine the location of the center of mass of an arm bent at right angle as per data given.
Step 1 of 4
Concept:
Center of mass(CM) of a body is an imaginary point at which whole mass of the body is supposed to be concentrated.We consider that the net force acts on the centre of mass of body, insteads of considering that it acts on each and every point on the body for simpler calculation and this is one of the importance of application of CM.
The location of the center of mass on the x-axis and y-axis is given by
and
