Tack. Enda personen på youtube som förklarar det konkret och enkelt. Mycket uppskattat även 10 år senare.

Is it possible to have a simulation demonstration for this, say in Comsol or other software?

at 8:30, the equation of w1/w2 does not make sense if b2 = y1. I think there is a mistake on previous slide . Vn2 should be equal to d2/2*w2*cos(b2). It is apparent from the figure also. Vn2 is in cosine direction.

Why during initialization we chose column 3 (with n1) as basis column? I dont get it.

Great presentation of AFM data interpretation

Borde inte energin vid grundtillståndet vara noll?

Great to hear this lecture. It support me a lot

Thanks for making these videos

Detta var 9 år sedan!

Thank you Professor for your step by step professional explanation. It is great!

Bra förklarat. Förklarar bättre än Fredrik Lindmark. Hade kollat hans och han bara babblade istället för att visa såhär👍

Värdelös genomgång

Elevator Motor ----As for the gear box, it is a small box that contains oil and has two gears... The first is a helix gear, which is connected directly to the motor and is the driving gear... The second is a regular gear with teeth that connects to the drive gear, which is the driven gear... A box was manufactured. The gears are engineered in this way, so that the motor can always move the gear wheel, and the gear wheel cannot move the motor even if the brakes are applied... This method is very safe and smart, so that a rapid fall of the cabin does not occur at all, even with the brakes applied.

Very good, my colleague

🤣 I was looking for a quick simple way to estimate Hertzian ellipse and found my old good supervisor explaining this on RUclips. Feels just like old good days way back! Thank you, Roland!

Excellent video, would it be possible to add references to the equations, just to know their sources and derivations. Many thanks!

First + rep

tack så jättemycket

What y_r in force balance term represent?

Just to say sir, wonderful lesson ever since i graduated from university. Big Thanks!!

Really good material! It helped with my master's degree.

Thank you, your lecture is very meaningful to me.

To other students, On slide 17, I think f(x_i - delta x/2) is a sign typing mistake for f(x_i + delta x/2). However, there is no problem understanding this lesson. This lecture is very kind. Keep studying.

I guess in initial few minutes in solved example; effective radius should be 17.5mm. Correct me if I am wrong?

perfect explanation, now everything. is easier thanks a lot

kung e du

Gong go ging gang

Very useful info

Aeh fyfan va du flåsar

I facit står det ju dock att A är 0,27 mikrometer och B 0,67 mikrometer vilket inte stämmer överens med din video

shouldn't it be 0.579GPa ??

How have you got 57.9GPa from 579MPa

energiskillnad=Eföre-Eefter och i uppgiften så står det att den ändras från ett exciterat tillstånd till ett grundtillstånd, varför är energiskillnaden inte =-2-(-15) då?

This is a great video, do you have resources available for computing the graphs shown at the beginning of the video?

Väldig duktig video

Thanks a lot! Very helpful!

I would like to create a analytical modelling between friction and lubricant

Thanks a lot

Dear Mr. Roland Larsson, Thank you for the neat and explanatory presentation. Do you think coating would get stuck more efficiently on the surface that was obtained too smooth? Couldn't we conclude coating on smooth surfaces is less desirable?

The explanation regarding the wedge taking the oil into and later out of the gap is just horrible.

Good explanation. But on you gubernatorial u need a voice or else hire someone

Don't u eat well? Can't u dpeak louder? Spineless voice

Thanks!

Tack så mycket. Förklarade det så mycket bättre än mina lärare!

How do you do that, which software?? Please tell

How to download this software
