Mechanical engineering Definition and 553 Threads

I'm now at my sophomore year in college, studying Mechanical Engineering. When I chose this field, I was interested in things like aircrafts and my main goal was working in the aerospace industry. This interest has shifted towards control systems/robotics since then. I started dealing with...

I'm currently a rising sophomore in college on track for engineering. I have to say, I love solving math problems, especially Calculus. I love Calculus. I started to take physics classes and I started to lose interest, mainly because its difficult and requires a lot of extra time to study, time...

I'm now heading towards the fourth semester in my Mechanical Engineering course, and I think it's a good time to start thinking about summer internships. Where I live, those usually happen in January-February, and companies start advertising their internship programs in september. I think it...

Where can I find one of these? That is, are there linear actuators where I can specify the force it should apply and it gives me back exactly how much force was applied? Are there any linear actuators that can do this and also give me position feedback, i.e., where my object is after it has been...

Can anyone please provide me information about the career as a nuclear physicists after B.Tech in Mechanical Engineering. is it a viable option?

I'm hoping to do a foundation year for mechanical engineering next year, can anyone recommend to get this book in preparation for it?: https://www.waterstones.com/book/foundations-of-mechanical-engineering/anthony-johnson/keith-sherwin/9780412616006 Thanks

Hi, I am doing a design project but I'm kinda stuck with choosing motors because i am not sure of the required torque. My project is a handicapped golf vehicle powered by 2 motors, so it would need to be able of climbing steep gradients. I currently have an equation but I am not entirely sure if...

I really do love the idea of engineering and being able to design and build such things. I'm currently in 12th grade about to graduate. I am going to a two year college before transferring out but I'm struggling to decide my major. I'm taking physics now and I love it, I think it's a great...

Homework Statement Shown in picture Homework Equations So far just used w=v/r The Attempt at a Solution [/B] Could only do part a. W=v/r =0.3/0.2 =1.5rad/s For part b I would assume the velocity is zero? But I don't think that's correct. Any help with part b and c would be great, and is...

I'm wondering how should I do analysis on those problems below: Figure 1: Figure 2: I mean, my professor, while doing an example very similar to Figure 2, he didn't do an imaginary cut in the region BD to find internal forces there, and the internal forces diagram that he drew only contained...

I really like Mechanical Engineering. I'm now at the second year of my undergrad and I'm now taking some specific courses in engineering - after a whole year of calculus and physics. I think it's the broadest engineering, and I'm an admirer of the aerospace industry and would like to work with...

Hi, I am a soon to be mechanical engineer with a big interest in electrical stuff and physics in general.

Hello, fellow mechanical engineers. Care to spend some time to answer a few of my questions? 1) What is your biggest struggle of being a mechanical engineer? 2) What made you choose this field? 3) What is your advice towards future mechanical engineers? 4) Do you regret being a mechanical engineer?

I am a second year student at Salt Lake Community College. About to finish my associates of science pre-engineering. I transfer to the University of Utah in the fall to start my junior year and I am kind of freeking out. I have worked my tail off. I work a full time job and take night classes...

Currently pursuing a degree in Mechanical Engineering, and commonly ponder about how much of this semi-abstract math I will actually be using the workplace. I have heard real-world ME relies pretty heavily on linear algebra and differential equations. As far as advanced Calculus goes I...

I am preparing for a qualifying exam for my PhD program and am looking at some of the old tests from previous years (as supplied by the school for study/prep material). I have come across a deflection problem that has me stumped, and I might just be overthinking it. The problem:

I'm a sophomore of Mechanical Engineering, but I do like delving into more advanced subjects that I haven't seen in undergrad yet, and among those are fluid dynamics. I've made a little bit of research into turbomachinery (while looking for some classes that could interest me hereafter) and...

Hey people, I need some help, preferably from the Electrical Engineers... Classes start next month and I'm stuck deciding some electives to take during my third mechanical engineering semester. Here's the thing: I decided to take some electives from the EE department so I have a good basis to...

I am driving 2 different gears with a belt off of a stepper motor that has a step angle of 0.018 degrees. For the purpose of my project, I need to have high precision between the stepper motor and the gears that it's driving. Is it necessary to have 20,000 teeth (360/0.018) on the gear that's...

Hey people. First of all, I'm now in the third semester of my course in Mechanical Engineering. I have interest in aerospace/aeronautics, so there are plenty of things in mechanical that I like - fluid mechanics, aerodynamics - and that was the reason I choose this undergrad. Nonetheless, I do...

I'm now at the second year of my MechE course. Until now, I've taken basic classes in physics, calculus, linear algebra and basic computer programming. I choose to undergraduate in Mechanical Engineering because I'm aware that it is a good and broad degree and it's a field that I like also. It...

Hello I'm curios to know if any of you have been affected by my current situation. Currently I go to school and major in Mechanical Engineering, I live on my own(with a roommate) have a full time job and go to school all at the same time. I wouldn't be doing all of that if I didn't have to but...

Hey everyone. I'm a student of Mechanical Engineering right now and even if I'm still a few years ahead to choose a field to major in, I like to have something in mind to focus on. First of all, I really appreciate the aerospace field. Airplanes and spacecraft were my main motivation in...

I've been giving a look at some of the electives in my college - I'm a student of MechE - and became interested in Control Systems, specially after I borrowed some books in the subject in the library and read a little bit more about it. I wonder how big is the field of application of this...

I've been discussing with some friends of mine recently and one of them pointed out that all senior engineers end up more involved with management stuff than actual engineering work. I know that, in some cases, that is not correct, but even so, I wonder if the big opportunities in an engineering...

Hello there, I have a few questions concerning how the choice between electrical and mechanical engineering influences one's future career if going into the aerospace branch - if possible at all. Can you do a Master or graduate in aerospace engineering with an undergraduate degree in one or the...
