The washing machine structure shown in the figure is as follows; rotating drum and The laundry is in a non-rotating cylindrical outer body (a non-rotating cylindrical 'tub'). Your laundry including wet state and additional mass (ballast mass). Considering the entire assembly, it is 40 kg and It is supported using spring and damping elements in the body (Case). In this case The natural frequency of undamped free vibration is 5 Hz for vertical motion. The damping factor is 0.2. The design speed of the machine is 1200 rpm. It should be noted that the maximum possible magnitude of imbalance is 0.2 kg.m It is predicted that it will be. At design speed (1200 rpm) (a) the vertical vibration displacement of the non-rotating cylindrical outer tube to the outermost body (will be assumed to be constant) (b) find the total vertical force transmitted to the constant outermost body, (c) what would be the amount of force transmitted if the drum and cylindrical body were rigidly connected to the outer body; What is the amount of insulation? (d) Explain the reason for the introduction of ballast mass Forces other than vertical forces will not be taken into account.
