How to set up
String passed through a tube , with a bung at one end, and LOAD AT OTHER END
Ruler to measure raidus, and clock for time
Methods
Whirl the bung with a raidus, with enough frequency such thst thr weight is held
Find the time period standard
This will allow you to find the VELOCOTY
Now vary the raidus and repeat
Plot v2 over r and will give a straight line throigh origin
What will the centripetal force be
Be the same as weight?
How to emsudre radius
Stop the radius or mark and emaudr sworn a ruler
How to vary the mass method
Keep radius constsnt, vary mass and then measure the feequnyt time period and thus v
Here and plot v against m
Yeah so vary raidus, and you’ll automatically have to change speed to match weight of centripetal force, then measuee time period for r and plot them
Remmeber take readings when removing msss
To check unloading curve and see if the wire hasnr been plasticslly deformed
Remember why rubber
Still elastic, area under graph represents work done, hysteresis loop suggest that nkt all thr energy is returned, when load is removed, some ke is transferred to thermal,mehich educes thr bounce
Describe properties
Hooked law, hysterics and elastic plastic
Oh yeah when using f =kx or your modkisnwhats the assumption
Is that hooked law not exceeded
