he centrifuge shown in the figure rotates in a horizontal plane (the xy plane) on a smooth surface about the z axis (which is vertical) with an angular acceleration a. Each of the two arms has weight w per unit length and supports a weight W 2.0wL at its end.
Derive formulas for the maximum shear force and maximum bending moment in the arms, assuming b= L/9 and c = L/10.
