•
Micrometer +/- 0.05mm
•
extension/length +/- 0.5mm, with a ruler
•
measuring extension at right angle due to pulley.
•
calculations involving g, +/- 0.05ms^2
•
friction of pulley
•
clamp and pulley being in line which may cause the wire to not be taught.
•
bench i was working on was loftsided and wobbly.
•
Equipment was used by the school so there may be minor defects.
•
attaching tape to the wire to measure extension may not be accurate enough.
•
Yield point of wire
•
The wire may not be taught
•
Keeping the meter to measure displacement level.
•
One of the scales on the meter was missing so i had to blue tack a ruler to it instead.
•
Slight friction on wrapping the wire round at the top.
