On rubber wedges modeled as spring and damper electric motor with mass M placed in damped free vibration it has been observed to oscillate 6 in 1 second when released, and the degree of damping is known to be 0.15. a) calculate the natural frequency of the system. b) calculate the mass of the engine, given as K=50000N/m. c) Moe imbalance in the rotor while the engine is rotating at 1000 rpm because of its value, the engine was observed to vibrate at an amplitude of 4 mm. Calculate the moe imbalance value of the rotor? d) the amplitude of the force transmitted to the ground while the engine is rotating at a speed of 1000 rpm calculate.
