Plane polarized oscilation of a spring

AI Thread Summary
To determine the energy E of a spring oscillating in a pure second harmonic motion, the mechanical energy is the sum of kinetic energy (Ekin) and potential energy (Epot). The frequency Omega can be derived from the spring's elastic constant k and mass M, using the formula Omega = sqrt(k/M). The amplitude A of the oscillation is given as 1 meter, which influences both the kinetic and potential energy calculations. The total mechanical energy can be expressed as E = (1/2)kA^2, where A is the amplitude of oscillation. Understanding these relationships is crucial for accurately calculating the energy of the system.

Hi All,

Suppose you have a spring with a given elastic constant k. Its natural width is L = 1 meter and its mass is M = 0.1 kg. Now imagine you put this spring to oscilate, with its ends fixed, forming a pure second harmonic oscilation, plane polarized, with frequency Omega. The amplitude of this oscillation is A = 1 meter also.
How is one to determine the energy E of this system ? (mechanical energy of this system E = Ekin + Epot)

P.S. it seems natural that the frequency Omega is to be determined from the constants I alluded above.

P.S. 2: by second harmonic I mean a sine function between the end points (x = 0 and x = 1) with just one crest and one valley.

Best Regards

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
