Two springs with the same unstretched length, but different force constants and are attached to a block with mass on a level, frictionless surface. Calculate the effective force constant in each of the three cases depicted in the figure.
a). Express your answer in terms of the variables k1, m, k2
k_eff -c =
b) An object with mass , suspended from a uniform spring with a force constant , vibrates with a frequency . When the spring is cut in half and the same object is suspended from one of the halves, the frequency is . What is the ratio ?
Express your answer in terms of the variables k and m
**Any solution I have attempted to part B has prompted an automatic response of "answer does not depend on the variable k or m" Which confuses me to no end.
Any help on this problem would be VERY appreciated.© BrainMass Inc. brainmass.com October 24, 2018, 10:51 pm ad1c9bdddf
Two springs connected in three different ways, the equivalent force constant is calculated.
The ratio of the new and initial frequencies is calculated when the spring of the oscillator is cut in two equal parts.
Simple Harmonic Motion: Springs in series combination.
See attached file.
In Fig. 15-36, two springs are joined and connected to a block of mass 0.245 kg that is set oscillating over a frictionless floor. The springs each have spring constant k=6430 N/m . What is the frequency of the oscillations?View Full Posting Details
