MESSAGE MY OURCES Chapter 10, Problem 045 lem The body in the figure is pivoted at O, and two forces act on it as shown. If r on it as shown. If r1 = 2.65 m, r2 = 3.49 m, F1- 2.65 m, r2 3.49 m, F1 5.07 N, F2 = 3.03 N, 1 = 62.0°, and 2 = 60.0°, what is the net torque about the pivot? lem lem tu Number Units the tolerance is +/-2% Click if you would like to Show Work for this question: eShWer Question Attempts: unlimited SAV' OR LATER Copyright © 2000-2015 by John wiry & Sons, Inc. or related companies.

Explanation / Answer

torque = r x F

torque net = r1 x F1 + r2 x F2

at point O

tnet = r1F1sintheta1 - r2F2sintheta2

tnet = 2.65 x 5.07 x sin62 - 3.49 x 3.03 x sin60

tnet = 2.70 N.m (out of page )
