Why is there the number 4 before the area law?
What the hell is going on there? What's k? How can a deflection be found by dividing a force by a random constant k???
this is so perfect
i dont understand the second question. i thought when finding the area of the bearing stress it is the area of the shaft exerted on the plate. so wouldnt it just be pi*(25)^2. why are we subtracting areas?
Fantastic ❤❤
You are a legend. Thank you so much 😊👍
i like it
very nice

On question 2/22 why did we take t=0.0185 instead of t=0.0386?
You guys have saved my exam grade
What book did you get this problem?
What is difference 53 and 54 I don't understand no.53 BD change to no.54 BD+0.25
why we use strain(permanent)=0.05-0.003? shouldn't we take just 0.05, because elongation for that stress is 0.05?
what book is this?
شكرا❤
Why was the max yield point provided for brass but not for the steel?
thank you so much \
How Vmax become 5kN?
wondering same thing
I love you right now.
thank you! this is better than chegg
Thank you very much this video is very useful for me
Why is there no horizontal force at B?
B's support is on a roller so there is only a vertical force.
Normal force would be the opposite direction/sign as your result (since it came out negative from equilibrium equations) I believe
Never put music like that in a video, its very annoying
thank uuuuu
Thank you
there is a mistake in the moment calculation, there is no direction chosen. If they do choose a direction for the moment this will result in a singular equation meaning everything cancels out so you probably should choose a different body for the FBD.
that guitar is nice haha
Please work it 2/111 2/126

In the first exercise, how did you get the value for G?
I’m not entirely sure if G will eventually change down the line, but at this point G for steel is always 75GPa. There should actually be at the back of your textbook (assuming that you have one). It’s titled Average Mechanical Properties of Typical Engineering Materials.

Como obteve 3??
why we substitute inner radius from outer radius
Why is the diameter pi/4 * d^2A specifically why is it pi /4 instead of pi(r)^2
which version of the book ?

thnx , it helped a lot ❤ I hope you solve ch3
hi can you teach us this quetion? F5-8 The gear motor can develop 2250W when it turns at 150 rev/min if the allowable shear stress for the shaft is t allow =80MPa , determine the smallest diameter of the shaft to the nearest mm that can be used.
