You're an absolute legend mate. Honestly.

usual excellent tutorial . Well done Jack.

The video content is so excellent, congratulations

Great video as always! Could you please explain as to why we cant use F=Mu x R. Didn't quite understand what 'limiting equilibrium' means. Thanks

Sir I have a question.Here the value of friction is 28.9 N and the normal force at bottom is 100 N. So the resultant of this two force is 104.09 N something . But this force is acting 73.8 degree with vertical between friction and normal.That means the ladder does not apply force along it's incline.if it gives force along it's incline then the friction and normal are different in this case.
Sir please solve my doubt...Love from India.

What if the top of the ladder overhangs over the vertical surface it’s leaning against? Would the normal reaction at that top point be perpendicular to the ladder instead of the wall?

Do we need to know about ladders for the aqa spec? Can't seem to find it in my textbook.

[samellis]

These questions stink so this video was a big help. you're the man jack 👍

[chewypiano]

when do we know if reaction force is angled compared to when it is perpendicular???

Thank you very much 🌹🌷
You solved a very big problem for me 💙❤

[johnlynch]

Did you remove the ladders section on your website? Why?

[alanmohan]

Does ocr need to know how to do hinges problems?

Hi, I've just seen a past paper question where the ladder is resting on a smooth vertical wall, and the reaction force between the wall and the ladder seems to be perpendicular to the ladder (jn the mark scheme) rather than horizontal, as I would usually draw it. Could you explain why this may be? Thank you
