INTRODUCTION:
F | = | longitudinal force in newtons | |
A | = | area in square meters | |
L | = | elongation | |
L | = | length of wire undergoing the elongation (not the total length!) |
SUGGESTIONS:
PROCEDURE:
QUESTIONS:
Note that the wire fails at a stress which is 100 x less than Young's modulus. Can you understand why the two values are not inconsistent? (Hint: If the stress equaled MY, what would be the strain?).
Could you notice the decrease in diameter of the wire in this experiment by use of a micrometer caliper? If so, try it.
