Erm... that is not the formula for moment of inertia I'm afraid... I'm not sure what it is...
What is M? And m? and F(x)?
The moment of inertia is given by:
where the integrals are taken over the relevant area of mass M, r is the distance to the origin, and dm is an infinitesimal amount of mass.
Do you know how to evaluate such an integral over the area given to you?
my graph was something like this: http://i.imgur.com/tso7y.jpg
Guess i have many thing to study
im not good in integrals and area yet
Hmm, I guess you have tried to define the boundaries of the area in question.
Let's start with the boundary given by:
This is an inequality that defines a circular disk of radius 1.
However, I do not see that in your drawing.
Or am I misunderstanding?
