WebNow, the list of solutions to forced vibration problems gives. For the present problem: Substituting numbers into the expression for the vibration amplitude shows that. Example 2: A car and its suspension system are idealized as a damped springmass system, with natural frequency 0.5Hz and damping coefficient 0.2. WebThe reduction in the relative velocity from V r1 at inlet to V r2 at exit causes some pressure rise over the rotor. The absolute velocity at exit V 2 can be found by vector difference between V 2 and u 2. The absolute velocity at exit V 2 makes an angle α 2 with the direction of motion. The air then enters the next stage via stator blades. stella mccartney patent ankle boots
