Note at minute 56 onwards is probably one of the most valuable synthesized and elegant pieces of information that you could ever see in your career as an engineer. If he added some of st venant's principle it would have been absolutely perfect. Very useful video.

What is the absolute viscosity range for which the charts are designed I tried with the operating temperature of 120degree C the clearance values are not matching with the defined design clearance

what is the bood reffered for equations please ? thanks

Thank you for these videos, my question is how do you know that you need to calculate the torque to make the motor turn at a constant speed, and what makes this condition be the maximum speed?

Brilliance. You have made this concept crystal clear to me. The reveation that the segment of 48:30 to 50:26 has given me, has sincerely made my day. Thank you for ending my confusion spiral. God bless you.

Firstly, thank you very much for the videos, I didn't give enough attention to these topics in time and now I realize that I need to study more and your videos are very helpful. One point I am confused is that at 18:26 you said that as theta_y goes to zero, normal vector will point towards y. However, this also implies that y component goes to zero. As we have F_y = F.cos(theta_y), actually theta has to go ninety degrees so that we will eventually have no F_y component. Am I thinking wrong?

Tremendous lecture, thank you indeed!

subscribed immediately

Thank you for clear explanations :)

Absolutely amazing explanation!!!

thankyou

Question and please reply.. What is the fracture toughness of brake pads and brake disc? Please answer ?

Can I sleep with you? Sincerely your one and only… ANGST!!!!!💀😍😍🔥🎉🔥😱💀

Why did you not account for the bending caused by Mx and the shear caused by Fx?

Over the years, I've studied numerous video compilations devoted to GD&T but always gravitate back to the TheBom_PE series. Anyone interested in learning GD&T from scratch should watch this video series in order and read Chapter 20 on GD&T in Shigley's Mechanical Engineering Design. I cannot think of a more thorough and comprehensive starting point.

Sorry to ask. Do you have a playlist with MathCad 15?

Does that extra twist during torquing reduce the final axial stretch of the fastener or is it negligible, if using a torque spec for installation

Can I get your e-mail address? I would like to stay in contact with you if possible. Thanks in advance Vladimir Grigorov

Hello, I am a graduate mechanical engineer and I work with SolidWorks. At the moment I am learning finite elements and I am enthusiastic about her lessons. You are the best teacher.

I'm confused by the units of Kb at timestamp 28:38 being MN/m. Isn't the answer 5,546,445,738,000 N/m or 5546 GN/m? Edit: Nvm, I realized 78mm^s is not 0.078m^2.I'll leave this here in the event anyone else comes along and makes the same mistake.

Hello Prof. [ At 8:29 we said current is leaving node 1 into node 2; and so, we defined it as positive got it. Then at 11:01 we said there is current leaving node 2 into node 1]. We defined both to be positive: leaving their respective node. I originally thought this made sense because we are just letting the math work itself out. For every node, if we don't know, just say it's leaving the node. Got it. But then [at 37:40 we said current is leaving node 1 into node 2. Got it. But at node 2 we said if current is *entering because we just said for our node 1 equation it is leaving. That also makes sense]. So, between these two problems, why did we approach it differently? What if for problem 2 we did what did we problem 1 and just kept it positive instead of intentionally defining it negative like we did in question 1? Would the math just work itself out, or would there be a bigger problem? Thank you.

Due to some mental health struggles, (I'm doing so much better now) I'm taking my Machine Design II class into the summer as an incomplete. Its been a time trying to learn everything off of the textbook, and when I get confused random websites and scattered youtube videos. I was struggling HARD with this section for a few days before finding your video. I cannot say enough how grateful I am that this exists. I learn a lot better watching videos, and this is exactly what I need to stay on track to graduate on time. Thank you so much!!!

Can you please explain why we modelled the normal force to be acting at two points? I believe a more accurate representation would be a distributed load across the triangle's base, with a larger normal force towards the right end of the triangle. Love your videos as you explain concepts very well, thank you.

Thanks I still want more examples

Thank you so much sir ❤

Hello professor, I am curious if you have any insight here. I just finished the halfway point of my MechE degree though a local community college. The only class I did not take there was Circuits I. I will be taking this in the Fall of 2024 at my 4 year. I am watching this playlist over the summer to prepare - thanks for posting! However, here is the actual question: at my actual 4 year, MechE's take their own level 3000 Circuit class - which is different from what the EE's take. I could have taken a general Circuit I class, that both MechE & EE take together, and transfer out. I'm curious if you know what, if any, the difference is between a level 3000 Circuits class is taught through the MechE department vs. a standard circuits I class. I assume they are more or less the same - but clearly there has to be some kind of difference. If you don't know, don't stress it. Thank you for making this great playlist.

Example 2 was truly a beautiful problem. Thank you for sharing!

I think he made an error on the last discussion of self locking screw, if your required torque to lower the load is positive, it should mean that is a self locking situation (it is not going to be moved by the load weight and the force of gravity), but if the required torque needed to lower the load is zero or negative it means that the load being moved by its own weight is greater that the resistance offered by the friction of the screw, and if the motor is not kept energized and in an electrically "locked" situation the load by itself will make the screw turn and lower itself, I really appreciate these lectures being online and available to everyone, great they share the knowledge.

Why the radiant units were removed when converting from 1n-lb/sec to H.P.? Was he missinsg some units from the conversion or result?

Sir, can you explain how to find a Brinell Hardness number when it's not given to you

It’s like music to my ears. Absolutely interesting to listen and maturing of explaining techniques and communication is another level. Fantastic 🧠 Was a FnDT engineer for 4 years… feels stupid being a robot without a deep understanding after listening to you .. Bless this lecturer. 🙏🙏🙏

Thank you Pro. That's fantastic. Your lecture really gave me a solid foundation. ❤

very helpful video thanks sir

Nice Videos ! Was hoping CIT ! Thinking of doing a Physics Deg. there. Wondering what I will be missing f/ ME & EE as a Physics Major. I like Machinery & Circuitry. Did EM Drafting for 13 yrs. All 4 yrs in HS I took Drafting + 2 yr Deg. AP. I hate to do Physics and never use the skill again.

Hi, which book are you following, please? Great classes btw

Can you please suggest a reference book?

Great lecture, but wtf are those units. Just use international standards.

Watching second time. Big respect to you professor. Not only on your knowledge but of course your teaching style and explaining every detail to ones whichis not a nerd or genious like you.

Sir i can't thank you enough for suggestions during assisted problem solving. Lots of love and respect from india

Sir it's the best explanation i've ever heard. Thank u so much for your efforts. Lots of respect and wishes from a learner from india.

Strange to grasp that both omegas are zero, but both alphas exist when t=0. We should take in consideration following: alpha = d(omega)/dt which means that we need infinitesimal amount of time, in order to define alpha. However, there is no change of omega in time because t=0, but regardlessly alpha exists anyway. So, where alpha is coming from? If we say that rod remains in horizontal position at t=0 and the rope is taut, then such a set up should be treated as a static problem (at this instant). In other words, (massive) rod and RIGID (massless) rope should be modeled as a rigid static form, supported at the point E. Any infinitesimally small passage of time, would cause appearance of both omega and alpha.

thank you Sir, this is useful in my studies.

Best video on 3D stress states so far🙏

Hi TheBom_PE, Hi want to build a platform for keeping 2000 Liters x 2 water tanks. Platform is approx 5 x 10 feet. Pillars will be in brick mortar and I want I beams on it to support load. What sizes of i beam and how many in numbers to use?

very clear! thanks 🙌

Bolts Pretensioned to specified torque Eliminates stress reversal and resulting fatigue cracking in fasteners . Bolts stay in constant tension .
