What is Spring block: Definition and 26 Discussions

Spring Street (originally Calle Primavera) in Los Angeles is one of the oldest streets in the city. Along Spring Street in Downtown Los Angeles, from just north of Fourth Street to just south of Seventh Street is the NRHP-listed Spring Street Financial District, nicknamed Wall Street of the West, lined with Beaux Arts buildings and currently experiencing gentrification. This section forms part of the Historic Core district of Downtown, together with portions of Hill, Broadway, Main and Los Angeles streets.

    Calculate the spring constant of oscillating mass on a spring colliding with a wall

    So I proceed as: Total time for 1 oscillation is 0.2s $$\frac{1}{\sqrt{2}}=\sqrt{2} \sin ({\omega t_1})$$ $$\sqrt{2}=\sqrt{2} \sin ({\omega t_2})$$ Therefore $$\omega t_2=\frac{\pi}{2}$$ $$\omega t_1=\frac{\pi}{6}$$ $$\omega ×2(t_1+t_2)=2×\left( \frac{\pi}{2}+\frac{\pi}{6}\right) $$ Since...

    Problem of spring block system: force vs conservation of energy

    I have used the work energy theorem like all source have shown me an have arrived at the right answer where work one by all the forces is the change in kinetic energy -1/2kx^2 - umgcosΘx +mgsinΘx = 0 is the equation which becomes -1/2kx -umgcosΘ+ mgsinΘ = 0 where k= spring constant u=...

    Maximum extension in a system with two blocks separated by a spring

    the acceleration of the center of mass is ##a_{cm} = F/(M+m)## I considered the forces on the block of mass m(when the system is at maximum extension) I got the equation $$kx - \frac {mF}{(M+m)} = ma_{cm}$$ and from that I got the value of the maximum extension $$x = \frac {2mF} {k(M+m)}$$ which...

    Maximum compression of a spring?

    I found the amplitude of the simple harmonic motion that results (0.367, and I know this is correct because I entered it and it was marked as a correct answer), and assumed it would be the same value for the maximum compression since x(t) = Acos(wt). And, since the maximum value of cosine is 1...

    Energy Conservation of a Vertical Spring

    Using conservation of energy, 0.5kx^2=mgh=mgx 0.5kx=mg 0.5kx=mg, x=0.15, m=9, g= 9.8 So isn't it k= 1176N/m? For this problem, I understand that you can't use conservation of energy, but why? There is gravitational potential energy at the top and spring elastic energy at the bottom, and no...

    Find the point of separation in SHM

    In the given problem, i can understand that after placing the two blocks in equilibrium it oscillates with an amplitude of The answer for (b) is given as To my knowledge, m2 separate from m1 when the acceleration is greater than gsinø and so they should be separating only at max displacement...

    Is Equating Energies a Better Solution for Finding Extension Under Spring Force?

    Its a very basic problem and my friend suggested a solution that we should equate mg and kx ie mg=kx and just plug in m=8 and x=0.16 but i think that we should equate the energies like mgx=1/2kx^2 ie because at the point where mg will be equal to kx the mass will still have a velocity hence it...

    Vibrations: A momentum impulse starts a mass into oscillatory motion

    The fig. 1.1(a) is a mass m attached to a spring that is fixed to a wall. I don't understand what does "a sudden momentum impulse" means. Is it an external force o what? I imagined that the new equation of motion would be md^2x/dt^2+dp1/dt-kx=0 md^2x/dt^2+mdv1/dt-kx=0 is this the equation i...
