machine mounted on elastic supports, is free to vibrate vertically. The machine has a mass of 40 kg and rotor out-of-balance effects are equivalent to 2 kg at 150 mm radius. Resonance occurs when the machine is run at 621 rpm. the amplitude of vibration at this speed being 45 mm. Determine the amplitude when running at 500 rpm and find the angular position of the out-of-balance mass when the machine is at its highest position during vibration.

mo A 100 kg machine has an unbalanced mass of 1 kg, which is rotating at a constant speed of 500 rpm at an offset of 0.2 meters. Calculate the amplitude of the centrifugal force that will be acting on the ground if the machine is directly anchored to the ground. Also calculate the stiffness of the elastic pad that will be placed under the machine such that only 1/10 of this force will be transmitted to the ground. 0-ot m
Derive the differential equation of motion for the system shown in its equilibrium position. Neglect the mass of link AB and assume small oscillations. Use the values m1=22 kg, m2=31 kg,k=800 N/m, c=163 N·s/m, a=340 mm, and b=610 mm and calculate the damping factor
A spring extends by 5 centimeters when loaded vertically with 2.5kg of weight. A new weight of 1.75kg was attached to it and was displaced 6cm from its new equilibrium position and was released from rest. Determine the frequency of vibration in rad per second?
A block having a weight of 8 lb is suspended from a spring having a stiffness k = 40 Ib/ft. If the block is pushed y = 0.4 ft upward from its equilibrium position and then released from rest. What is the amplitude of the vibration? Assume that positive displacement is downward
A weight attached to a spring of stiffness 3.0 lb/in has a viscous damping device. When the weight is displaced and released, the period of vibration is found to be 1.80 seconds and the ratio of consecutive amplitudes is 4.2 to 1.0. Determine the amplitude and phase angle when a force F-2cos(3t) acts on the system.
