Problem

A uniform rod of length

0.60\,\text{m}

and mass

2.0\,\text{kg}

is hinged at one end so it can rotate in a horizontal plane. A force

\mathbf{F}

is applied at the free end, making a

30^{\circ}

angle with the rod (measured between the force direction and the rod). If the rod is initially at rest, determine the magnitude of

\mathbf{F}

required to give the rod an angular acceleration of

15\,\text{rad/s}^2
