A smooth circular cylinder of radius \(\displaystyle b\) is fixed parallel to a smooth vertical wall with its axis horizontal at distance \(\displaystyle c\) from the wall. A smooth uniform heavy rod of length \(\displaystyle 2a\) rests on the cylinder with one end on the wall in a vertical plane perpendicular to the wall. Show that its inclination \(\displaystyle \theta\) to the horizontal is given by

\(\displaystyle a\cos^3\theta+b\sin^3\theta=c\)

Please help

Re: statics

Two things:

1. Could you please post a picture of the situation?

2. Could you please show what work and ideas you've had?
