- Determine a natural frequency of vibration as a function of k₁, k₂. g and W of a spring-mass system placed on a inclined plane as shown in the figure:arrow_forwardA 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 downwardarrow_forwardThe uniform beam is supported at its ends by two springs A and B, each having the same stiffness k. When nothing is supported on the beam, it has a period of vertical vibration of 0.83 s. If a 50-kg mass is placed at its center, the period of vertical vibration is 1.52 s.

- A spring has a spring constant of k=18N/m, hung with a weight of mass m=½ kg. If the load is in an equilibrium position, then it is pulled and released with a speed of 3 m/s, then determine the equation of motion of the object if it does not experience friction or damping.arrow_forwardA 2.3-kg object is suspended using two linear springs (k1 = 45 N/m and k2 = 21 N/m), as shown below. Due to aerodynamic effects and other losses, you observe that the amplitude of the vibration is halved after 5 complete cycles. If the initial mass was displaced 270 millimetres below the equilibrium position (i.e. negative initial displacement) and then released from rest, determine the position of the mass after 11 seconds. Give your answer in millimetres rounded to one decimal place. Enter positive values if the mass is above the equilibrium position and negative values if it is below the equilibrium position. k karrow_forward3 m 1 m 1 m Determine the natural period of vibration of the pendulum if it is given a small displacement and released.

- k The 8.8 kg block is attached to a spring (k = 214 N/m) as shown. The small wheels serve to eliminate friction between the block and the surface, but can be treated as massless. The block is displaced an initial distance of 1.6 m with an initial velocity of 6.1 m/s. This causes the system to undergo free, undamped vibration. Determine the equation representing the position of the block, x, as a function of time, t. Then use this equation to determine the position of the block at 2.2 s.arrow_forwardA coil of spring stiffness 4 N/mm supports vertically a mass of 20 kg at the free end. The motion is resisted by the oil dashpot. It is found that the amplitude at the beginning of the fourth cycle is 0.8 times the amplitude of the previous vibration. Determine the damping force per unit velocity. Also find the ratio of the frequency of damped 'and undamped vibrations.arrow_forward2. The mass ? = 20 kg is suspended from an ideal spring of stiffness ? = 500 N/m. If the mass is set into motion at ? = 0 with the initial conditions ?0 = 45.5 mm and ?0 = −104 mm/s, calculate (a) the amplitude of the motion; and (b) the time when the mass stops for the first time. Assume that ? is measured from the equilibrium position of the mass.arrow_forward

The mass of the scales is small and the damper is chosen to give critical damping when a 10-kg object is weighed. If a mass of 20 kg is placed on the scales, what is the damping ratio and how many cycles of vibration will occur before the reading on the scales settles to within 1% of the correct value?arrow_forwardA 3 kg mass suspended from a spring having stiffness of k= 200N/m. if the block is pushed 50mm upward from its equilibrium position and then released from rest a) Determine the amplitude and the frequency of the vibrationarrow_forward
