I have managed to rearrange an equation give to me to make I (moment of inertia) the subject. I am now having problems working out the values for parts of it.
I = moment of inertia
m = mass
g = gravity
h = height
v = translational speed of the mass falling
Tf = work done against friction
theta = angle through which flywheel rotates in radians
w = rotational speed of the flywheel
The equation is I = (1/2mgh - mv^2 - Tf * theta) / w^2
I am finding it hard to work out a value for v and w. is 'the translational speed of mass falling (v)' is that just a fancy way of saying velocity?
I am unsure of how to find a value for w
Hope this makes sense
Thanks
