    Nonzero net force involving no displacement. Is this accurate?

    Thanks everyone for the input! This is really helping me conceptualize this. I think my confusion was from me clinging to the tendency of a force to move something a given distance. Where if the distance moved is in a circular direction, there's really no displacement involved, whatsoever. I...

    Nonzero net force involving no displacement. Is this accurate?

    So I am studying mechanical engineering, and I got into a debate with my (mit mechy) graduate roommate about the possibility of having a net nonzero force which involved no actual displacement of an object. Normally, when an object is accelerated along a direction (given an external force)...

    Automotive My engine was smoking the other day

    rangermike, pretty solid explanation. I don't think most of those would cause a significant amount of smoke to rise from the hood like he was saying. While possible, it would be extremely rare, and problems in subsystems including powersteering, clutch and the brakes system would fail long...

    University Admissions Essay reference, I need your opinion!

    ^^ yes, i'm aware of the fact that "math/science" does not make grammatical sense, I was just trying to communicate a message, and I won't do something like that in the essay. :smile: Grammar isn't something I typically care for in a forum, rather, getting the message across. I'm also going to...

    University Admissions Essay reference, I need your opinion!

    Ok. What if i considered it a trade off between pure theory and physical application. Does that sound more accurate? I can see how the term "compromise" might marginalize the skills of an ideal engineer.

    Automotive Alternate approach to Engineering (opinion please!)

    Thanks for the response Chris. It was kind of a shoot-down though, haha. I understand it is virtually impossible for every component (particularly in the engine package) to have a perfectly accessible spot. And that more biased opinion only makes it more difficult to draw a consensus on the...

    Automotive Alternate approach to Engineering (opinion please!)

    This is not a re-post of my other thread in general section, so please understand. First, a brief description of myself: I'v gotten my associates degree in Automotive Technology/Repair, with perfect scores. ASE certified. But I have always been an aspiring Mechanical Engineer, with assisted...

    How does a turbo use heat from the exhaust?

    Steamking is 100% right. You must focus on the prime phenomenon at work here. Heat particles are expanding as they leave the exhaust valve, which pushes in all directions, if you think about it, this natural phenomenon is somewhat counter-efficient to the structure of an engine. Turbochargers...

    Automotive Torque/hp philosophy (infinant gear ratio)

    ok ok ill give you that one, not a bad idea ill admit. I don't think they always misunderstand the meaning, but they limit their experience to traditionally geared transmissions, where nowadays aftermarket transmission suppliers are involving larger varieties of gearing/clutch setups. You can...

    Automotive Torque/hp philosophy (infinant gear ratio)

    Thats only because Im trying to come to a consensus among people. I think I made 1 or 2 other threads about this, and that was several months ago, do you really loaf around the forums that much to give a f***? Cmon.

    Automotive Torque/hp philosophy (infinant gear ratio)

    Another person from a similar thread said something that I thought was interesting: Given a conventional geared transmission, supposedly best momentary acceleration is at peak wheel torque. This comes from F=MA, arranged as A=F/M. Acceleration is highest when force (torque) is highest. Based...

    Automotive Torque/hp philosophy (infinant gear ratio)

    I am still trying to visualize horsepower and torque seen on the racetrack, and its hard. Obviously torque is a component of horsepower. Without enough torque, a car would take forever to reach its power-band. With a lot of torque, but merely no horsepower, a car would have a very steady...

    Automotive Another hp v tq thread this ones optimistic

    OK, I'm seriously struggling with this horsepower torque conflict, mostly because of all the god damn bias going around in these forums. It seems that the facts only go so far as to saying hp is a measure of power, and torque is a measure of turning force, then when people try to bring about...

    Endothermic absorb energy How do they begin in the first place?

    Endothermic absorb energy... How do they begin in the first place?? PLEASE, BEFORE ANSWERING I would like you to hear me out. >>> Im really confused as to the phenomenon of why endothermic reactions between mixing of two substances just spontaneously happen.. giving them temporary "cold"...

    Folks, how do you meause or an equation to

    ^^ he is right, just as i was saying. Finding the density of an alloy wheel is almost never used in engineering of car/suspensions in the first place.. It might really hard to find out the density value of a lambo rim in the first place.

    Question about tan, cos, and sin

    yeah I think you may be misunderstanding the context of tangent. Often in calculus a tangent line is used to represent instantaneous rate of change at a given point. The trig functions sine cosine and tangent are different, they refer to the relations of a right triangle on the coordinate...

    Re: Please, help me me better "understand" physics/math proportions thank you guys very much for giving me some insight. I will take these things into account, and i look forward to hearing more from those of you. Although I have yet to begin my calculus series, It seems most people only...

    Folks, how do you meause or an equation to

    That is exactly my point. given dimensions of rim size and width isn't NEARLY enough information to get what you want. That information alone would give you the volume of the entire rim including the 90% of volume that isn't taken up in the inside of the wheel. Those dimensions are used...

    Folks, how do you meause or an equation to

    due to your extremely vague question, I dont think anyone knows what your talking about. Lamborghini wheels are like any other performance car wheels as far as i know. There are only subtle differences in mass or volume, mostly being the technique lambo used to apply their paint to the wheel...

    (at the most fundamental level) why does energy release upon chemical reactions?

    Please don't be bothered by my question, i know it sounds real elementary and it could easily be researched, but after doing so, i haven't been able to find anything on how or why the natural phenomenon of energy release takes place as chemicals react with one another. If you think about it...

    Automotive How electron flow is in a car system

    I think if you have a solid understanding of how your multimeter/voltmeter works, it can help a lot when trying to learn these things about electricity flow, with the redundancy and whatnot. Study ohms law and just make it strictly intuitive that automotive industry observes electricity through...

    Is this the career for me?

    ^^ i like this answer lol. but i still think you can totally manage to have a social life while taking the several years of study at hand. Its just harder, you cant let social gathering offerings seem "inconvenient" to the moment of in-depth studying. You have more control over your study time...

    Automotive Why not CVT? Its ingenious to say the least.

    Ehh, "costs too much:" sounds like a market based answer. It just seems like the materials used are so much more simplified than automatic transmissions. I actually drove one today in a nissan maxima before aligning.. just the typical 3.5l found in most (PLENTY of power by the way... just...

    Automotive Why not CVT? Its ingenious to say the least.

    Most of us are familiar with the continuously variable transmission. Disregarding reality for a minute, I think one should understand that the crucial components of making something (anything) turn at variable speeds requires that of a POWER SOURCE.. (engine) and its counterpart of a MEANS TO...

    for sure man, just remember, if you want to go mechanical all the way.. theres hella math and physics skills you've gotta be good at. Calclulus 1 2 3 as well as differential equations and mechanical/electrical physics are the typical curriculum agenda before you even start your dynamics and...

    Automotive How performance car parts influence torque vs horsepower?

    THANK YOU EVERYONE for the replies, i never get bored of hearing about these kinds of things.
