Problem #4) The extremities of a 4-ft rod weighing 50lb (1.5528slugs) can move freely and with no friction along two straight tracks. The rod is released with no velocity from the position shown, resulting in the rod to slide down the incline. The angular acceleration of the rod is a = +2.30k rad/s² and the linear acceleration at point A is 12.5674ft/s² to the right. Determine (a) ao, the linear acceleration at point G, and (b) RA and RB, the normal reaction forces at point A and B.

23. In a spring controlled governor, the radial force acting on the balls was 4500 N when the centre of balls was 200 mm from the axis and 7500 N when at 300 mm. Assuming that the force varies directly as the radius, find the radius of the ball path when the governor runs at 270 r.p.m. Also find what alteration in spring load is required in order to make the governor isochronous and the speed at which it would then run. The mass of each ball is 30 kg. 80 mm 60 mm A 80 mm stor lo auiber ors +a b-

Consider the wheel shown below with radius R, mass m, and radius of gyration ko¹ The wheel rolls without slipping under the action of a clockwise torque M. At the instant shown the spring with spring constant ks is unstretched. Derive an expression for the velocity of the wheel center of mass G after the center of mass has moved a distance d. (Hint: Use rigid body work-energy principles. The work done to the system by the applied moment is McA0 and A0 can be related to the distace d by the no-slip condition.) Us G R M м, ко ////
