The spiral spring was suspended vertically from a rigid support.
|
| 2 |
Loads of 50, 100, 150, 200 and 250 were taken in lower end of spring
and the extension ws measured in table-I.
|
| 3 |
Time for 10 oscillations were taken in table-II for each load added
using stop watch.
|
| 4 |
The load was slightly displaced vertically to produce small
oscillations.
|
| 5 |
The mean extension and mean time were calculated. |
| 6 |
Grpah was drawn for table-I, loads in x-axis(10 small box = 50) and
mean extension in y-axis(10 small boxes = 2), a straight line was
drawn. Two points were take that in straight line precisely cuts
through both axes.
|
| 7 |
Another graph for table-II, with load in x-axis(10 small boxes = 50)
and meann time in y-axis(10 small boxes = 0.1). The straight line
was drawn from x-axis point 26.5.

The mass was taken, along with a, from graph using formul. |
| 9 |
Spring constant(k) was calculated. |
