An accelerometer is composed of weight W = 0.042 lb suspended by a spring for which k = 5 lb/in., and the fluid damping factor for the instrument is zeta = 0.65. when used on a machine vibrating at a frequency of 13.647 Hz, the instrument reading for the maximum acceleration is 50 in/sec^2. Determine fhe correct value of the maximum acceleration of the machine

Title Plot the solution of a linear, spring and mass system with frequency ?n = 3 rad/s, x0 = 1.2mm and v0 Description    Plot the solution of a linear, spring and mass system with frequency ωn = 3 rad/s, x0 = 1.2mm and v0 = 2.34mm/s, for at least two periods.  Compute the natural frequency and plot the solution of a spring-mass system with mass of 2 kg and stiffness of 4 N/m, and initial conditions of x0 = 1mm and v0 = 0mm/s, for at least two periods.

2. The machine shown below, with the rotating unbalance, operates a speeds between 18 and 60 rad/sec. Determine the minimum value of damping coefficient c needed to keep the amplitude of vibration below .3 inches. M = .026 lb sec2/in m = .0026 lb sec2/in r = 2 in.
