4. A uniform disc of mass m = 3 kg and radius R= 0.5 may roll without slip on the 30 degree incline shown. An elastic spring of stiffness k= 100 newtons/meter is connected to the center C of the disc. Initially, the disc is held in place in the position shown, with the spring neither stretched nor compressed and with the disc at rest. At t = 0 the disc is released and is subjected to a constant force of Fo = 30 newtons along the incline. Determine the maximum speed achieved by the disc center C as the disc moves up the incline. For gravity use g = 10 m/sec². (note: initially the constant force Fo will be greater than the forces exerted by the spring and by gravity, and the disc will accelerate up the incline; but there will come a distance x along the incline after which the spring force + gravity will overtake the force Fo, and the disc will then decelerate). gravity Fo= 30 N 30° no friction

A 20kg slender rod AB is pinned to a roller at A that slides freely along the slot as shown in the figure below. The rod is released from the rest at an angle of 30. At the same time, a couple moment of M = 5 N.m in clockwise direction is applied at its centre of gravity. If immediately after the release the acceleration of the roller at A is 43m/s, determine the reaction forces at the pin connection at Point A.
