In the figure, a ladder of mass m is shown leaning against a wall. It is in static equilibrium making an angle theta with the horizontal floor. The coefficient of friction between the wall and the ladder is mu1, and that between the floor and the ladder is mu2. The normal reaction of the wall on the ladder is N1, and that of the floor is N2. If the ladder is about to slip, then:
A) mu1=0, mu2(not=)0, and N2tan(theta)=mg/2
B) mu1(not=)0, mu2=0, and N2tan(theta)=mg/2
C) mu1(not=)0, mu2(not=)0, and N2=mg/(1+mu1 mu2)
D) mu1=0, mu2(not=)0, and N1tan(theta)=mg/2

Pease refer to ncert system of particles example.... Same question but tricky one 😂😂😊

[@MichelvanBiezen]

One day when we have the time. At this time we have our hands full.

[@Yashbansal1511]

THANKS PROF. I WAS SEARCHING FOR THIS QUESTION THEN I FOUND YOUR EXPLANATION😊😊

[@MichelvanBiezen]

You are welcome, glad you found the video.

[@Brandon-305]

Mr. Van Biezen do you have a playlist for Electrical Engineering in Associates level mainly control Systems? Thank you.

[@MichelvanBiezen]

We do have electrical engineering videos, but we haven't covered control systems yet.

Why is sum of torques equal to zero in those two cases?

[@MichelvanBiezen]

If there is no angular acceleration, then the sum of the torques must be zero.

[@wannabefighterpilot]

The rod is about to slip so we can consider equilibrium at this instant

You're welcome!

Mr. Biezen: Your brillant. I'm a nut brain because other stupid paths were taken instead bettering myself while in the formative years. Thank you for the countless illustrations and spot-on mathematics. -----E Structural

A viewer sent me the quote a few days ago: "The best time to plant a tree was 20 years ago and the next best time is now". It is never too late to enrich oneself with learning new things and gaining new experiences. Who is to say that living a simple life is not better than living a complicated life? I would like to retire and move to a place with some land so I can learn how to farm and raise animals.

Thank you so much 😀
