A washing machine produces disruptive noise during its spin cycle due to an uneven distribution of clothes around its circumference. To reduce the noise, an engineering consulting firm has proposed that the machine be mounted on spring isolators at each corner (four in total). The machine has a capacity of 10 kg of laundry, an unloaded mass of 450 kg, a drum diameter of 0.50 m, and spin cycle speed of 955 rpm. To address the noise levels, the transmitted force should be reduced by 75%. Assume vertical vibrations only and that is inherent to the system (damping from the spring isolators are negligible)
