(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

[tex]\omega=constant[/tex]

[tex]R=0.2m [/tex]

[tex]\theta=30°[/tex]

[tex]\mu _s=0.5 [/tex] between the iron cube and the surface

[tex]\omega_{max}=?[/tex]

2. Relevant equations

Fx=Fsin(α) or cos(α)

Friction=µN

3. The attempt at a solution

in pink I drew the gravity force and the normal force.

Which other force acts on the body? the friction force is directed along the surface, but in which direction going towards the center of the cone or outward? Why?
