Two rods are connected by a collar at

b. a couple ma with a magnitude of 15 n∙m is applied to rod ab. knowing that the coefficient of static friction between the collar and the rod is 0.30, determine the largest couple mc for which equilibrium will be maintained.

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
