Question:
The change in kinetic energy ΔE of an engine is 300 J, and minimum and maximum shaft speeds are wmin = 220 rad/s and wmax = 280 rad/s, respectively. Assume that the torque-time function is purely harmonic. To achieve a coefficient of fluctuation of 0.05, the moment of inertia (in kg.m2) of the flywheel to be mounted on the engine shaft is

- A vibratory system consists of mass m, a vertical spring of stiffness 2k and a horizontal spring of stiffness k. The end A of the horizontal spring is given a horizontal motion xA = αsinwt. The other end of the spring is connected to an inextensible rope that passes over two massless pulleys as shown. Assume m = 10 kg, k = 1.5 kN/m, and neglect friction. The magnitude of critical driving frequency for which the oscillations of mass m tend to become excessively large is ____rad/s (answer in integer).
