Moments of inertia Flashcards
1
Q
When finding the moment of inertia, we break shapes up into smaller shapes. What moment of inertia do we now consider?
A
Moment of inertia about shape we broke object into
2
Q
When using parallel and perpendicular axis theorum, what do we do when summing values?
A
Keep them in terms of dm as we are working with infinitesimal objects and not M as a whole
3
Q
What two things have to be compared when dealing with angular motion?
A
Linear and angular impulse
4
Q
Equation for angular impulse?
A
Fxtxr = Iw
5
Q
Equation for linear impulse?
A
Fxt = Mv
