Homework Statement
As the picture shows, we are given several variables, but I am near completely lost. I am behind in my course and am trying to catch up as best as I can but this problem is really hard for me
Homework Equations
The equations that I have used are;
parallel axis theorem
angular acceleration = tangential acceleration*radius
The Attempt at a Solution
I know that this solution will be completely wrong as I haven't utilised the frictional torque, nor the angle.
So, by applying the parallel axis theorem for the mass moment of inertia;
I0 = I + mr^2
I(slender bar) = 1/12 * m * L^2
∴ I0 = 1/12 * m * L^2 + mr^2
then used the fact that:
ƩM0 = I0:
and therefore:
mgb = I0 * angular acceleration:
where b is the distance from the COM
however, as assumed, this gave the wrong answer, I'm really stuck with it and I want to know how I can do it for problems to come. Thanks!! :D
