If you're wondering about how to figure out which sphere was hollow, just place both spheres atop an incline ramp and let them roll to the bottom (without slipping). The hollow sphere will come last. Both spheres start with the same graviational potential energy, mgh, and we know that all this energy is converted into rotational and translational kinetic energy. The hollow sphere takes more energy to rotate around its center because all of its mass is distributed on its surface, and moment of inertia is proportional to the square distance of each mass component. Therefore, the hollow sphere will use more of its energy trying to rotate and less energy into translational motion, making it reach the bottom of the ramp last.
@@Hon2fun They have the same mass and the same external volume… so they'll both behave the same in water. Even if they weren’t the same weight, things of different weights and densities can behave the same way in water. A solid ball of glass and a solid ball of lead would both sink
@@xenontesla122 Hey thanks for your reply. I have been a test engineer for over 5 years now and this is how I measure and determine characterstics of different objetcts using specific gravity.
Your videos are some of the most informative I’ve found for engineers on RUclips! Thanks for sharing all this and talking about your experience so honestly. Appreciate it a lot!
Hey man, I know you’re into tech companies and the startup community, but why not try automotive? Great number of fulfilling jobs in mechanical design engineering, and a lot of innovation on the horizon!
@K1NG_GTR35 yea I agree. He should go for some sort of automotive, energy, or construction job. Some of those jobs can pay well (good enough) and be fulfilling.
24 yr old sophomore mech engineering student here, this all sounds really intimidating, challenging, and discouraging lol. Thank you for providing value :)
Amazing video as usual Tamer! You described all the struggles and quirks of each interview round very well. I was able to truly relate from my experience with the hiring process at Tech companies.
5 interviews for a mechanical engineering job is beyond insane tech companies have to have some serious lack of peoples skills to have to do 5 interviews
My theory on why the hex sockets are the standard is that it allows more angles to turn a screw in a tight space. You can rotate every 60 degrees, vs a triangle socket would only allow you to reinsert every 180 degrees
I know this isn't the place to look for a job, but imma give it a shot since they say the best way to get a job nowadays is by recommendation by networking. So if anyone has free time and has a potential opportunity for me I would love to talk to you so you can give me a chance. I am a recent grad with 0 internship experience but if you're willing to give me a shot you won't be disappointed since I am highly committed. Comment on this message to get in touch
Recentaly I went to an interview for a company that I didn't really care about. it was more like a practice to me. Process was nice and an engineer did the interview which was great. Problem for them is that I am currently working for another company and they needed someone right away. So they said that I was disqualified because of that? wut. This is the second time this happens, they want somebody that is not working? haha. that makes no sense but whatever

Coupd you also do a drop test, compare how they react when it hits the ground?
you can also just throw them both in water see which one weights more

Even mining, oil&gas, construction
Right he always going for Apple, google and dumb meta. They don’t even care for people
Ah yes autosar, how exciting

I love how down to earth and real your videos are Tamer, you are an inspiration!

As a guy going into Waterloo Engineering next year, been binging your vids recently, W stuff
Love your videos man great advice for me in future in engineering
You should make a part 2 to this video where you go over the onboarding process once you get hired.
if you are wondering about the notebook , buy from dollarama much cheaper or exactly same price but no delivery charges
The honesty is always nice to hear.

U mean a flat head screwdriver only allows for 180 right?
Very helpful,and i found the test very drastic,have even had time to think before answering to their questions?
He plugged temu 😭

Do you guys that side also have to wait for 3-4 years experience in order to be a professional engineer upon graduation?

Hey do tech companies hire Civil Engineers
Do you know Charles or Rony Azrak
Apart from linkedIn where eelse can we get job ads
Newspapers
Imagine Being ghosted after 9 houra of an interview OMG😢
Any interview longer than an hour should be paid time...
How u so chill after getting abused by these companies.
Why you got so big dark circles 😮
So funny hearing the Afrikaans accent in the muffled interviewers voice
Give those recruiters another job! They can't even speak
Tamer, are u Egyptian?
Pakistani
