Probably the most detailed explanation I could find on KZbin. He is so clear and careful about the use of his terminology. Awesome :)

Hello Prof. Bom, I am a 57 year old Mech Engineer who is studying for my second attempt at the PE exam. Passed the FE 30 years ago, and then took the PE 5 years back without sufficient prep, due to work schedules. Work life hasn't changed, so I am short on time again. I watch your lessons at 2X speed and you're still remarkably understandable. What digital white board software are you using? I am very grateful for your channel.

I'm glad my content is helping! I use Microsoft onenote 2007... the last version before the stupid ribbon bar. Best of luck on your re-take!

@@TheBomPE I recently learned that I did pass the PE Mechanical: Machine Design and Materials at 57 years old and 6 months after Covid hospitalization, and without a prep course. Your videos helped in several ways. While they were very time efficient (esp. at higher playback speeds ;-), clear and comprehensive technical reviews, the positivity of your engagement with the students was also key to the motivation to keep on working. I can't emphasize how much an instructor's compassion, decency, humility, focus, disciple, organization, thoroughness, and accountability all contribute to a student desire/ability to persevere and succeed. Cheers.

When you do a free body diagram of the ABC or BDE bodies, why do the forces at location B give you the force and direction acting on pin B instead of the force and direction acting on the hole located at B on the body?

Example The structure connected to ceiling in the in gym is frame not truss? The loading is elevated side walk for walkers, garage door like doors with pulley & motors. basketball hoops.

hi teacher, how´s going, i´m here because i have a question , it´s about frames, there´s a problem where i have 3 forces in a pin, so i dont know how to analize, the problem looks like an estructure is shaped like a rhombus , so i have 3 forces in a pin and reactions where they´re not applied in the pin....i dont know how to do that

I had a question. In a frame of equilateral triangle .with ABC points A being left start point and has 100 grms of weight On B side if 100grms of ball is connected with rope How do I lift the ball on A with B . How to reconstruct the Fram

Im sorry for the first example wouldn't the vertical component be sin and the horizontal be cos? Also for the Ra for the Fx equation how did you determine or why'd you plug it in as a negative and for the Fy equation why'd you plug in as a positive? How did you know it was negative and positive instead of flipped because it gives different answers.

Its so hard to not make a mistake with these kinds of problems like I accidently when drawing diagram 2 forgot The applied 6 kn load and it messed up all of my other work. Ive been practicing these problems for a while and sometimes i get it all right but like more than half the time i make some small mistakes. I write down the wrong perpindicular distance or I Add instead of subtract. Its really hard!

@roobear5357 10 ай бұрын

Notice how the professor is methodical in doing the problem. He doesn’t rush ,he writes and draws neatly and he double checks. It’s an engineering problem not just a math exercise. So approach it as if people’s’ lives depend on you getting it right. Good luck!

@chrismarklowitz1001 10 ай бұрын

@roobear5357 Yeah I've had more experience now some things I've learned are 1)Don't assume I know how to do a problem or even a step. I find that when I see something that I've seen before I'll immediately start writing stuff down but instead if I act as if I've never seen it I'll be more methodical. And I'll think through it more. This is probably the biggest thing 2) Don't get distracted/forget Sometimes I'll read part of the problem then get distracted trying to figure it out. Or I'll be mid way through a problem and I'll get distracted solving part of it and forget the rest. So I need to not let myself get sidetracked, follow an order and not assume I'm done

Hello, why is newtons 3rd law not applied to the 50lb force D at 1:27:52? I thought it would be going downward.

@TheBomPE 2 жыл бұрын

Newton's 3rd law says that every action has an equal and opposite reaction. That's why the force vectors flip direction between two bodies that are applying force to each other. That's what is done in the example here.
