SUMMARY

The discussion focuses on determining the inclination angle $$\theta$$ of a smooth uniform heavy rod resting on a smooth circular cylinder, which is fixed parallel to a vertical wall. The relationship governing this inclination is established by the equation $$a\cos^3\theta + b\sin^3\theta = c$$, where $$b$$ is the radius of the cylinder, and $$c$$ is the distance from the cylinder to the wall. Participants seek visual aids and further elaboration on the problem-solving process to enhance understanding.

PREREQUISITES
  • Understanding of basic statics principles
  • Familiarity with trigonometric functions and their applications
  • Knowledge of smooth surfaces and their implications in physics
  • Ability to interpret and create geometric diagrams

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

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

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?
