1. ### Rotation Question?

About the center, the moment of inertia of the rod is Ic = M(3L)²/12 = 3ML²/4 and so by the parallel axis theorem, about the pivot point it's I = 3ML²/4 + M(L/2)² = ML² torque τ = M*g*(L/2) = I*α...

2. ### Axes of Rotation ...1?

yup  good so far...  don't forget to choose a Best answer.... Though I like  tan (2@) = B / ( A - C )  = -4/3  we can work with cotangent also..  Draw rt triangle  in QII   [ in Q II since  cot = -  in Q II ] ......  i'll use...

3. ### Another Rotation Question?

As the load swings down to the equilibrium position, it converts PE to KE. The moment of inertia of the system is I = mL²/12 + 2m*(L/2)² = 7mL²/12 The maximum speed is at the bottom of the arc: 2m*g*(L/2...
