Hooke's Law Demo
Hooke's Law Demo
Kletzing Spring Constant Data

 

Code Number: 1R10.10

Demo Title: Hooke's Law Demo

Condition: Good

Principle: Hooke's Law

Area of Study: Mechanics

Equipment: 

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).

Procedure:

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.
