Young Modulus Experiment - Data Sheet

If you have a printer, print out this page to keep a record of your measurements and calculations.  If you do not have a printer, you could copy this sheet by hand.

Test wire dimensions (Experiment - step 2)

Diameter of test wire, D: 1. mm, 2. mm,
3. mm, 4. mm, Mean D: mm
Mean D: m
Average Cross-sectional area, = m2
Length of test wire, L: 1. m, 2. m, Average: m

Mass - extension data (Experiment - step 3)

Mass, M/kg 0 2 4 6 8 10
Extension, l/mm

Evaluation of gradient (Graph)

Gradient, equation_13.gif (119 bytes) = equation_16.gif (444 bytes) = mm kg-1
= m kg-1
Inverse gradient, equation_15.gif (117 bytes) = kg m-1

Result (Calculation)

Young Modulus, E equation_09.gif (197 bytes) = N m-2
