Equilibrium Problem: Standing on a Beam

Physics Ninja looks an equilibrium problem where a person stands on a beam connected to a wall and suspended by a cable. The tension in the cable and the reaction force from the wall is calculated.

Thank you for making the concept so easy to understand.

thank you for the help! This video really helped me in solving similar questions related to static equilibrium!

[chloelineberg]

great video! this helped my on my physics homework. thanks so much

Great tutorial! How about a horizontal beam switched to the right side, the same as the cable? Would the solution be the same?

Thankfully but the final answer is incorrect the correct one is 631N as the tension in the string but you have helped me too

Ninja! When calculating the toque are you not supposed to use the tension in the y axis?

[panisjohanesmarkg.]

Would you please explain further how it become 71°

Amazing video, very helpful, thank you

why isnt there a normal force on the ninja? also why not compression force?

...so this is a class 2 lever?...I am trying to figure out what kind a lever a tree branch is. I thought it was class 3...but looking at this video maybe it is a class two. looking at this diagram, a branch is more like a suspension bridge with multiple cables holding it up, maybe?

Why is rhe reaction not perpendicular to the beam

I mean I understand clockwise but I don't understand how u came out with the anticlockwise side only...maybe because u r not using figures

[sergiobaroud]

why do you simplify “L”, you should replace it with 8 and then continue with the calculations

[firdausbasrie]

what if, there are 3 sling / tension at the beam? how to get T for all slings?

[TinotendaNgwenya-fv]

Sir am not understanding your angle there

[natasyasajeii]

Do normal do not exist on ninja on a surface ? Thank you for anyone answering

How to calculate reaction when give horizontal will tension

[multi-talentwithgrace]

The only part I didn't understand is taking moment
