Elastic constant of a spring.

Planning:

  1. Introduction: The aim of this experiment is to find and measure the elastic constant of a spiral spring.

(b) Apparatus:

  1. Light spiral spring.
  2. A scale pan.
  3. A meter rule.
  4. 2 Clamps and Stands.
  5. 2 Boxes of weight.
  6. Light pointer for spring.
  7. Stop watch.
  1. Method:
  1. Suspend the light spring from the clamp and attach a light pointer to the spring.
  2. Set up a fixed vertical meter rule beside the spring using the clamp and stand.
  3. Attach a scale pan to the spring, and then add suitable weights, noting the reading of the pointer each time.
  4. Do this for about 8 loads on the scale pan.
  5. Then remove each weight, and record the reading of the pointer each time.

Conclusion

  1. Evaluation:
  1. Since I was using plasticine and a pin as a pointer, it was a bit difficult to get a perpendicular horizontal position for the pin to the meter rule.
  2. Also when you add weight on to the scale pan, the spring kept oscillating for some time before coming to rest. I ensured that at all time when I was taking my reading that the spring was at rest, and this made my reading accurate.
  1. Conclusion:

(i)     =      kg per meter extension is the mass hung on the spring per meter extension.

(ii) Since the graph is a straight line passing through the origin, the extension of the spring is directly proportional to the tension in the spring that is Hooke’s law.

    The effect however, is undetectable in large black holes as they have huge amounts of hot gas falling into them, emitting much more radiation than the black hole itself. Conversely, for small black holes the hawking radiation would be significant, giving the black hole a moderate glow.

    as that of the bottom of the spring, or else the measurement would occur at an angle and be in-accurate, determining at what level my eyesight should be at often proved slightly hard to determine. 4. Due to the method of attaching the parallel springs to the clamp and masses,

    This is the same for the other graph as well and they do show at one particular point in on the graph is where the extension and tension are proportional and Hooke's Law is applied. I think that this maybe able to be worked out using Hooke's Law formula but

  2. Investigating the Vertical Oscillations of a Loaded Spring.

    it is common sense that as the number of springs increases, the lower the frequency (number of oscillation in a given time), and as the number of springs gets fewer, the higher the frequency. The total amount of elastic potential energy and kinetic energy is constant; therefore there is always

  1. Study the interference of light using Helium - Neon Diode Laser.

    we have bright bands are C,E,G and dark bands at D and F. the bright and the dark bands placed alternately are equally spaced. These bands are also called interference fringes. If S is a source of white light, interference fringes are coloured and their width are unequal.

  2. Measuring spring constant using oscilations of a mass.

    I am going to vary the mass form 0.100Kg to 0.600Kg. In steps of 0.100Kg from smallest to largest. Safety Considerations * I would have to deal with the spring properly because I don't want the spring to bounce back and hurt someone.
