MHB Finding Inclination of Rod on Cylinder to Wall

Click For Summary
The discussion centers on determining the inclination angle, θ, of a uniform heavy rod resting on a smooth circular cylinder, positioned parallel to a vertical wall. The relationship between the rod's inclination and the distances involved is expressed by the equation a cos³(θ) + b sin³(θ) = c. Participants request a visual representation of the setup to better understand the geometry involved. Additionally, they ask for clarification on the work and ideas already explored in solving the problem. The conversation emphasizes the need for clear illustrations and foundational concepts in statics to facilitate problem-solving.

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

$$a\cos^3\theta+b\sin^3\theta=c$$

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?
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
