An Aluminium object is made of a solid cone of height 'h' and base diameter D attached to a solid cylinder of diameter D and height 'h/2'... condition for stable equilibrium?
- A. tan^-1 (10D/9h)
- B. pi/2 - sin^-1 (10D/h)
- C. pi/2 - sin^-1 (10D/9h)
- D. tan^-1 (20D/9h)
Answer: C. pi/2 - sin^-1 (10D/9h)
Explanation: Complex CG calculation problem. Requires finding composite CG and stability angle.
