As shown in the figure, a weight of W=4 lb rests upon a frictionless surface between two springs have a constants k1=1.5 lb per in and k2=2.5 lb per in. The weight is released from rest when it is % in from its equilibrium position. Determine the period of vibration and velocity as it passes through the equilibrium position.

Step 1
The formula for this is 1/keq = 1/k1 + 1/k2. Substituting the given values, we get 1/keq = 1/1.5 + 1/2.5 = 0.6667 + 0.4 = 1.0667. Therefore, keq = 1/1.0667 = 0.937 lb per in. Show more…

Consider the spring in FIGURE $128,$ but assume that because of friction and other resistive forces, the amplitude is decreasing over time, and that $t$ seconds after the spring is released, its position in inches is given by the function $$s(t)=-11 e^{-0.2 t} \cos 0.5 \pi t$$ How far was the weight pulled down from the equilibrium position before it was released?

A particle of mass $m$ is attatched to three springs $A, B$ and $C$ of equal force constants $k$ as shown in figure (12-E6). If the particle is pushed slightly against the spring $C$ and released, find the time period of oscillation.
