There are two forces we know, Centripetal force (or Gravity) and Centrifugal force. Both are applied to all the planets including earth. Planets are kind of spherical due to gravitational force but also not perfectly round due to this centrifugal force (or any other force idk) applied.
I read a lil before asking this question here and found, centrifugal force (or whatever) is not really great on earth but obviously it's enough to cause bend to it. But, I found this about Altair
A significant percentage of stars in the sky rotate much faster and bulge noticeably at their equators. Like Altair is notable for spinning very, very rapidly and completes a full rotation on its axis every 10.4 earth hours. Accordingly, astronomers estimate that Altair is at least 14 percent wider at the equator than it is from pole to pole.
I'm sure there must be many stars and planets with greater centrifugal force on them like Altair. But why then none of the planet or star is torn apart till now ? I mean less or more a force is applied and that force is making an impact and huge impact maybe in many cases. Then why none of such planet is torn apart till now ?
If you say Gravity or centripetal force keeping it together and maybe canceling out other forces then why even this bend ? that means other forces have an impact (if i understood it correctly).
I'm not a physicist but have interest in physics. Would be thankful if someone can explain in simple words.
