A uniform horizontal beam of weight 618 N and length 3.43 m has two weights hanging from it. One weight of 518 N is located 0.86779 m from the left end; the other weight of 418 N is located 0.86779 m from the right end. What must be the magnitude of the one additional force on the beam that will produce equilibrium

Acar traveling at 22 m/s starts to decelerate steadily. it comes to a complete stop in 15 seconds. what is it’s acceleration?

In automobile steering wheel is shown what is the ideal mechanical advantage blank? if the ama is eight what is the efficiency of the steering wheel?

Two steel balls, each of mass m, are welded to a light rod of length l and negligible mass and are initially at rest on a smooth horizontal surface. a horizontal force of magnitude f is suddenly applied to the rod as shown. determine (a) the instantaneous acceleration a of the mass center g and (b) the corresponding rate at which the angular velocity of the assembly about g is changing with time.
