Hey peoples... i have a quick question...

 

if i want to find the moment of inertia from a the gradient of a graph... and i have taken a whole lot of measuremants that vary time and mass... what would i do with these three equations: (i have been fiddling around with them for hours and getting nowhere, i was looking for a directly proportional realtionship but yeah....probably not the way to go i guess )

 

 

 

T is tension and so i suppose varies with mass

h and S and r are all constant , oh and g is constant too of course

 

equations:

 

 

any help, i'd love it!

You varied the time and mass of what, exactly?

Hey peoples... i have a quick question...

 

if i want to find the moment of inertia from a the gradient of a graph.

 

Moment of inertia of what shaped object?

 

And this graph, it was what vs what exactly? What were the units of the x axis, and what were the units of the y axis.

 

There is a formula for the tension of a string, and it has a mass density dependence, but I dont remember the formula for it offhand.

don't worry bout it guys, i got it now thanks for replying anyway though
