Ex. A 50 kg laboratory experiment is to be mounted onto a table in the laboratory. The table, which is rigidly attached to the floor is vibrating due to the operation of the other machinery Measurements indicate that the floor's acceleration amplitude is 1.2 m/s² and it vibrates at 100 Hz. Accurate use of the equipment requires that its acceleration amplitude be limited to 0.6 m/s².wx *=1 (a) What is the largest equivalent stiffness of a mounting of damping ratio 0.1 that can be used to limit the acceleration amplitude to 0.6 m/s²? z=1 (b) What is the maximum deflection of the mounting?
