If you pass a current through a conductive metal spring, it will compress. If you hang a mass m from a vertical hanging spring, it will stretch some distance x. Could you keep a vertical hanging spring with a mass m hung on it from stretching downwards by simultaneously putting electrical current into the spring? If so, how strong would the current have to be? Model the spring as a solenoid with length L and N turns per length.
A 0.50 kg object vibrates at the end of a vertical spring (k= 82 N/m). What is the period of its vibration? How far does the spring stretch when the mass is placed on it? What is the stored potential energy in the spring?
A light spring with a spring constant k = 316 N/m is attached to a vertical wall at one end and a block with a mass m = 0.462 kg at the other end. The block rests on a horizontal frictionless surface and is initially at the equilibrium length of the spring. The block is then displaced from the equilibrium position of the spring in such a manner as to stretch the spring by an amount A = 0.190 m...
You hang a mass of m = 0.500 kg on a spring and measure that it stretches 2 cm (0.02 m) from its original length. How much elastic potential energy is stored in the spring when it is at rest, stretched to this length?
Hang the 100 g mass on spring 1 and enter the additional
displacement of the spring
_____10______cm. Calculate the spring constant of this
spring___________ N/m.
3. Place the 250 g mass on spring 3 and change the “Softness”
setting to 1 notch to the right of the middle.
Calculate the spring constant of spring 3
:_________________N/m.
Note that the displacement of the springs with the masses attached
is the NEW equilibrium length of the spring. The restoring force of

a mass m is hung from a fixed support by a spring of constant
k whose natural length is l. a second equal mass is hung from the
first mass by an identical spring. we assume that only the vertical
motion is possible. find the normal modes for small oscillations of
this system from its equilibrium point.

1. A pendulum of length L and mass M has a spring of force constant k connected to it at a distance I below its point of suspension, Assume that the vertical suspension is rigid and that both the vertical suspension and spring are mansless (a) What is the frequency of vibration of the system for small values of the amplitude (small 0)? (b) If the pendulum is displaced by Omar and then released from rest, what is its kinetic...

Prob. 7.3: A simple pendulum (mass M and length L) is suspended from a cart (mass m) that canoscillate on the end of a spring of spring constant k, as shown in the figure at right. (a) Write the Lagrangian in terms of the generalized coordinates x and ?, where x is the extension of the spring from its equilibrium length and ? is the angle of the pendulum from the vertical. Find the two Lagrange equations. (b) Simplify the...
4. A weight of mass 100 gm (0.1 kg) is suspended from a vertical spring causing the spring to stretch so that the distance from the spring's point of suspension to the center of mass of the weight is 20 cm (0.20 m). If the spring and mass are rotated in a horizontal circle, how many RPMS does it take to stretch the spring out to the same length of 20 cm? r 20 cm In other words, how fast...
