A shock absorber is designed to quickly damp out the oscillations that a car would otherwise make because it is suspended on springs. Find the period of oscillation of a 1590-kg car that is suspended by springs that make an effective force constant of 5.55×104N/m. Find the damping constant b that will reduce the amplitude of oscillations of this car by a factor of 5.00 within a time equal to half the period of oscillation.
1. Suppose that a car weighing 4000 pounds is supported by four shock absorbers Each shock absorber has a spring constant of 6500 lbs/foot, so the effective spring constant for the system of 4 shock absorbers is 26000 lbs/foot.1. Assume no damping and determine the period of oscillation of the vertical motion of the car. Hint: g= 32 ft/sec22. After 10 seconds the car body is 1 foot above its equilibrium position and at the high point in its cycle....
Suppose that a car weighing 2000 pounds is supported by four shock absorbers Each shock absorber has a spring constant of 6250 lbs/foot, so the effective spring constant for the system of 4 shock absorbers is 25000 lbs/foot. 1. Assume no damping and determine the period of oscillation of the vertical motion of the car. 2. After 10 seconds the car body is 1 foot above its equilibrium position and at the high point in its cycle. What were the initial conditions? 3....
An automobile is considered as a system consisting of a mass-spring of single degree of freedom and dampener that makes vibration movement in the vertical direction. The car is driven on a road that its surface is sinusoidally changing as shown in the figure. The distance between the highest point and the lowest point on the road surface is 0.2 m, and the distance between two consecutive peaks along the road is 35 m. If the natural frequency of the...
Consider a single degree of freedom (SDOF) with mass-spring-damper system subjected to harmonic excitation having the following characteristics: Mass, m = 850 kg; stiffness, k = 80 kN/m; damping constant, c = 2000 N.s/m, forcing function amplitude, f0 = 5 N; forcing frequency, ωt = 30 rad/s. (a) Calculate the steady-state response of the system and state whether the system is underdamped, critically damped, or overdamped. (b) What happen to the steady-state response when the damping is increased to 18000 N.s/m? (Hint: Determine...
2. Consider the torsional system shown in Figure 2. Assume damping is negligible, i.e., ok/J. From the free vibration response, it is observed that the natural frequency of the system is w Then increase the moment of inertia of the disk to JJ, and the free vibration response shows that the natural frequency is reduced to a,2. Calculate J and k Express Jand k in terms of ω 1 and ω". Hint: Apply a, = vk/J to both cases. 0,T...
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
