Question
In exercise physiology studies, it is sometimes important to determine the location of a person's center of mass. This determination can be done with the arrangement shown in the figure below. A light plank rests on two scales, which read Fg1 = 400 N and Fg2 = 335 N. A distance of 1.65 m separates the scales. How far from the woman's feet is her center of mass?

Explanation / Answer
In exercise physiology studies it is sometimes important to determine the location of a person's center of mass. This can be done with the arrangement shown in the figure. A light plank rests on two scales, which give reading of Fg1 = 365 N and Fg2 = 340 N. The scales are separated by a distance of 2.00 m. How far from the woman's feet is her center of mass? sol: Let its distance from feet = x Therefore From other end distance of COM = 2 - x Therefore ,by Balancing the Torques about the COM, we get 340*x = 365*(2-x) Therefore x = 1.035 m
