hei man ,can you make an example of the problem of machine parts, in which you can explain how to choose a bearing in which the vertical, horizontal and axial force acts given by the angle of inclination of the gear teeth and what are the formulas that apply for that case and why apply like this

Is hardness in Pascals or Mega Pascals? If its megapascals why is it normal to bake them into wear coefficients?

you explain very poorly. You are not telling why sometimes we are just ignoring first bit and why sometimes we are adding first bit to number. Your methods are too experimental

thank you very much ,that was really helpful.

Up at 4am yahoo

Professor I have a question .It says if bearings are used in conjunction with other supports ,the couple moment reactions become redundant and are not shown on the free body diagram.I wonder if bearings' couple moment reaction become redundant or all the couple moment reactions become redundant.Could you help me?

how should the stimulation of this circuit work ? i mean which more additional inputs will be there with up and down because the outputs are not working according to the truth table with only two inputs

I got round beam (radius=7mm)(lenght=100mm) with 5kg mass dropping from a height of 3000mm and my impact factor is like 1540 and i wonder what is wrong.

what happens if the beam is not shaped like a box, but has another shape. Can it still be done with the same calculations and formulas? and does the contact surface between the ball and the beam matter?

How do i export stress and time also in export option in signal list

❤

Thanks Walter!

thank you

Hi there, if the whole system were to be rotated anticlockwise by 90deg (the ball travelling horizontally - like a canon ball) how could one calculate the static load to be then multiplied by impact factor to obtain the stresses and deflections of the beam? When travelling horizontally there's no static load like is when the ball falls down due to gravity...

thanks

Thanks! Would I consider the deflection due to the beam's own weight in calculating dst? Or do I only consider the static deflections that occur due to the impacting mass?

Sir kindly explain how can we use Archard's equation for the calculation of wear coefficient of pin sliding on plate? If sliding distance is not known, only known thing is the frequency, applied load and volume loss.

very grateful!

important to know that if the yield strength of the bolt is higher, then you use the yield strength for the ratio not the proof strength!!!!!!!!!

How to calculate radial loads for bearing calculation?

thanks a lot for this very well explained

the demon within me lusts for more than machine elements knowledge

On 8:18 you can enclose all 3 1's horizontally. That all together is one group. on Y1 row of what you circled

@5:10 why is 0+ 1+1 = carry 1 and 0 but 1+1+1 is carry 1 and 1? They are binary Numbers. 1+1 is always one. 1+1 = 1 -> +1 = 1. Where do you get 3 and turn into binary?

thank you so much

Which hardness value should be taken? In one case you have taken HB and in the other case you have taken HV, so numerically there is too much difference!!!

Thank you. You have helped me a lot! Appreciate your input!! Good work!

Good explanation Sir

How do you calculate the load, speed and travel for the test?

Hardness is a number then how you convert it in to megapascal. Can you please clear?

can ı reach the verilog code this machine

Can you make a video on effect of plotting graph to stud the effect o parameter on each other

Veyr nicely explained Dr. Thank you

Much needed topic

Excellent Sir..

Thanks for the video, helped alot.

If we have to calculate factor of safety for given materials, then how can we calculate it?

Very good explanation! Thanks, Dr. B!

Plizz can you do a video on three 3 bit digital lock

very unengaging

Could you tell me in which book did u find the equations?

I forgot to mention in the presentation that for maximum-normal-stress theory predicts failure will occur when the maximum-normal-stress reaches the Ultimate Stress (Su), however when the Ultimate Stress is not known, we use the Yield Strength (Sy) as the upper limit.

Dr. B, This was a great and thorough video! you walked me step by step and now I feel like i really got this down. Thanks for making this!

thank you i found this very useful.... :)
