Two Springs of constants ky and are connected in series to a block A that vibrates in simple harmonic motion with a period of 52 When the same two Springs are connected in parallel to the same block, the block vibrates with a period of 22 s. Determine the ratio Kyk of the two spring constants (Round the final answer to two decimal places) WWW . w The ratio of the two spring constant is
The ends of two identical springs are connected.
The ends of two identical springs are connected. Their unstretched lengths \(\ell\) are negligibly small and each has spring constant \(k\). After being connected, both springs are stretched an amount \(L\) and their free ends are anchored at \(y=0\) and \(x=\pm L\) as shown(Intro1figure). The point where the springs are connected to each other is now pulled to the position \((x, y)\). Assume that \((x, y)\) lies in the first quadrant.What is the potential energy of the thetwo-spring system after...

1. A suspension system shown in the figure is modified by adding two additional springs each with a spring constant of k, kN/m in addition to the other existing three springs with k 90 kN/m each. The design also adds two additional dampers in addition to the two existing dampers each with the same viscous damping coefficient c (= 4000 Ns/m). The viscous damping ratiofor the underdamped system, 7 is 0.95. The mass of the system, m = 150 kg....

A mass of 500 grams is attached to two springs whose spring constants are k1=2 N/m and k2 = 5 N/m, which are in turn attached to a wall. The system is on a horizontal frictionless surface. The system is displaced to the right and released. (a) What is the effective spring constant of the two springs in ”series”? Hint use Hooke’s law and the fact that the force required to displace the system is the same acting on each...
