Question

In this example, we show how to find the location of a person's center of gravity. Suppose your lab partner has a height! of 184 cm (6 ft, 0 in) and a weight w of 670 N (151 lb). You can determine the position of his center of gravity by having him stretch out on a uniform board supported at one end by a scale, as shown in the figure. If the board's weight wb is 47 N and the scale reading F is 3.15 x 10 2 N, find the distance of your lab partner's center of gravity from the left end of the board.

Explanation / Answer

670*x + 47 * 3 - 315 *6 = 0

x = 2.61 ft from left
