Question

So i have a question about how to find inertia. its from my lab and for some reason can't figure it out so here it is.... There is a weight(699g) that rest on a spindle and from this spindle a string is runs through a pulley to 50g weight that is hanging. The pulley is a smart pulley so it can read the velocity of the weight or the spindle moving. So what we did was have two different runs. With out the weight(699g) and with. My problem is i cant for the life of me figure out what the inertia is with out the weight. Here is the data and the calculations: plate- length 4.81cm width 22.29cm mass(as stated above)- 699g distance(m)-Velocity(m/s) without plate 0.15-0.084942 0.15-0.085697 0.15-0.087383 with plate 0.15-0.069672 0.15-0.070328 0.15-0.07147 radius of spindle- 4.005cm finding the hanging mass and kinetic energy: K=(1/2)m(v)^2 I(total)=I(plate)+I(assembly)->right here i can't find the assembly inertia!!!! I=(1/12)m(A^2+B^2) K=(1/2)I(w)^2 w=velocity/radius(spindle)

Explanation / Answer

unable to understand question, I have done this experiment in which there was a pulley whose inertia was to be measured with a given weight of block attached to it, here i am unable to get what is spindle, plate please make it more clear I am sure I can help with this
