1R10.10 - Hooke's Law Demo

See procedure.
See procedure.
Code Number:
Demo Title:
Hooke's Law Demo
Hooke's Law
Area of Study:
Matched springs (set) (steel), Spring (phosphorous-bronze, k=3.98 N/m), Spring (Savage's favorite), Masses (set), Vertical Measuring Scale, Spring scales (2) (Newton's), Stopwatch, Spring scale (kg).

When using the large springs at least 500 grams will need to be applied before they become linear.  After that at least 3 - 1 kg masses may be applied to the spring with linear results.  These may be measured with one of the meter sticks with large lettering.

A backboard with markings on it may be used for a more visual display of the displacement, although this probably will not work well in the two large lecture rooms due to the seating elevation.
