Hang a spring from a clamp stand along side a metre ruler
Measure the springs initial length
Add weights in intervals of 10N and record the extension
Plot a graph of extension against force
What piece of apparatus is used to secure the clamp stand to the desk and why?
A G-Clamp, so that the clamp so that the clamp doesn't tip over whilst adding masses
The clamp produces a moment which counteracts the moment cased by the masses so that the stand remains in equlilbrium (a state in which opposing forces or influences are balanced)
How do you calculate the extension of a spring when you add masses?
Subtract the extended length of the spring to the original unstretched length.
What can be added to a spring for accurate extension measurements?
