(Weight: 25%; CPL-h CPMK-2) The foot pedal mechaninsme for a machine is modeled simply as a pendulum connected to a spring as shown in Figure 2. The size of the parameters shown in Figure is m = 0.5 kg, g = 9.8 m/s2, 1, = 0.2 m and 12= 0.3 m. The function of the spring is to provide a return force on the pedal. Determine the spring stiffness needed to keep the pendulum deflection at 1º from its horizontal axis, then calculate its personal frequency. Assume the deflection of the pedal is small enough that the spring deflection can be considered equal to the magnitude of the deflection angle / arc length, the foot pedal can be considered a point mass, and the pendulum brick has a negligible mass. The position of the pedal will be on its horizontal axis when the spring is not given loading.
