1. A building exhaust fan for a large commercial bullding weighs 180 pounds and operates at a speed of 600 rpm. Due to manufacturing tolerances, it may have a rotating imbalance. It is desired to limit force transmissibility to 2.5 as the fan passes through resonance during startup and wind-down. In addition, an Isolation of 90% is required at the operating speed of the fan. The fan's framework will be supported from the floor at 4 corners. Design, select, and specify vibration isolators at the four corners. It is acceptable to assume the center of gravity is symmetrical with respect to all four corners, enabling you to treat this as a single DOF system without pitch or yaw.
In this system, there are two mass elements: m₁ and m₂. They are con- nected by a spring. m₁ is also connected to a massless rod, which can rotate at its midpoint. The other end of this massless rod is connected to another massless rod, which is connected to the ground through a spring and a damper. This configuration forms the basis of the system. You may assume small deflections for this problem and that the vertical connections are rigid links. When the coordinates y₁, y2, y are equal to zero, the gravi- tational force on the masses is covered by springs (the system is at its static deflection). Two input forces, fi and f2, are applied on the masses m₁ and m2 respectively. HINT: You should not consider the gravity force in your solution.

A helical compression spring is subjected to a maximum force, Fmax of 1250 N. The deflection of the spring corresponding to the maximum force should be approximately 30 mm. The spring index is 6. The allowable shear stress is 350 MPa and the modulus of rigidity is 81 370 N/mm². Design the helical spring by calculating the wire diameter, mean coil diameter, number of active coils and the total number of coils. State all assumptions and decisions in your design.

A helical compression spring is needed to fit over a 0.5 in. diameter rod. To allow for some clearance, the inside diameter of the spring is to be 0.6 in. To ensure a reasonable spring size, assume a spring index of 10.
