100-kg motor is supported by four springs, each of constant 90 kN/m, and is connected to the ground by a dashpot having a coefficient of damping c = 6500 N . s/m. The motor is constrained to move vertically, and the amplitude of its motion is observed to be 2.1 mm at a speed of 1200 rpm. Knowing that the mass of the rotor is 15 kg, determine the distance between the mass center of the rotor and the axis of the shaft.
Consider a vibrating piano string. The string is under a tension T, has a length L and diameter d. What is the frequency f' for the second string
A.) Write an expression in terms of the given quantities, for the magnitude of the bullet's acceleration, a, as it travels through the rifle's barrel. You may assume the acceleration is constant throughout the motion.
