Thank you! Made it very clear and easy to understand.

Would the friction at A not be downward because P pushes B in and A up? Thanks for the video it is really helpful.

how come when taking the sum of the forces you don't include the x and y component of the bar

I think the length of rod must be 5. Pythagoras is not happy
