No specific question.
How would one find the critical angle of a ramp given the mass of the block sliding down it and the mu between ramp and block?
It's not a single question but something my teacher explained that i didn't understand.
I'm not sure of any more
The Attempt at a Solution
I just don't get how to calculate the critical angle.
Is there a formula or a way to derive some equations?
What i know is i have to get the gravity vector that points down the ramp to exceed friction.
But how would i set up that equation?
