    Understanding spring mass system

    I am just learining basic dynamics from spring mass system. there is a horizontal spring fixed to the wall and a mass is at the end. When the mass is displaced by a force F to the right the spring stretches to a distance X. Now i draw the STATIC FBD. The eqn is f-kx=net force on the mass...

    Spring Mass System Approximations questions

    I have been trying to figure out why it's considered a "good" approximation in spring mass calculations to add 1/3 of the mass of the spring to the total mass of the system. I understand the need to add SOME extra mass (other than the mass of the weight added to the bottom of the spring for...
