Homework Statement hey guys, I've got an assignment and its asking me to explain why some materials to have the same toughness value, but quite differnt fracture toughness values? i really don't understand wats the difference between toughness and fracture toughness? any help would be...

Homework Statement The Earth and the Planet of the Apes are in a reference frame where they are stationary relative to one another, and are measured to be 2 light years apart. The observers on Earth send a TV signal to the Planet of the Apes with a picture of a banana. 0.6 years later, the...

i don't really have time to write out all my awnsers, but would appreciate if someone could give me the awnsers to these questions i'm confident in my maths but just need someone to give me a rundown of the awnsers, because the book I'm using dosen't have any! there are 12 questions in all...

Hey all! Just made a PF account and have this question on my mind... So I'm going into my 2A semester in January (because I'm in co-op and so I don't have the traditional schedule), and I completely messed up my first year at University. The reason was because I had to take 3 non-math...

Homework Statement If f(x)=x^x for x>0, find the constant a such that f'(a)=2f(a) Homework Equations The Attempt at a Solution f'(a)=a*a^(a-1) =a^a 2f(a)=2a^a 2a^a=a^a ln2a^a=lna^a aln2a=alna ...?

These are a part of your daily life. (couldn't find the best forum to post this in, but wanted to share it)

It's supposed to be an easy question, but I'm not a math major. Evaluate lim x-->0+ (√(9 + 17lnx + 9ln^2x) - 3√(1 + lnx + ln^2x)) , if the limit exists

I'm a first year mechanical engineering student at the university of Witwatersrand( known as wits university). I would like to know what I can do to ensure that I know a lot about what i am getting into. thank you:smile:

Hey everyone, This is my third day at university. I'm taking an Analysis course and I'm getting owned! I came from a relatively small high school in a small town and we hardly did any proofs at all except for proving trig identities. Now this course is all proofs; I thought I can handle...

I'm just wondering im going into 2nd year. ..I'm taking Analysis I, Differential Equations Calc III ,Probability all in the same semester and then Abstract Alg I , Linear Alg II , calc IV in 2nd semester Just wondering what I can expect for the differnet years...how much more intense it is

Hi, at the moment I am using the set book (Physics for scientists and engineers, Tipler) for my core physics modules at uni. However I want something which has roughly the same stuff in it but which will present it in a slightly different way. A good analogy is my use of maths books, I use both...

I'm about to begin a bachelor of science with a physics major. I've already found some books on electrodynamics and relativity and such, but I can't find the motivation nor resources to intepret some of the more abstract mathematics, especially to do with linear algebra, tensor analysis and...

Hi, second term is coming up, woot. I have e&m next semester and I heard that griffiths is one of the best texts around on numberable occasions, my university has it but it's not for my class but a senior class instead. I don't see why I need to use a certain textbook, I didn't for calc or...

A 70 kg overhead garage door consists of a uniform rectangular panel AC, 2100 mm high, supported by the cable AE attached at the middle of the upper edge of the door and by two sets of frictionless rollers A and B. Each set consists of 2 rollers located on either side of door. The rollers A are...

Hi, if anyone remembers I was the guy considering re-doing first year due to only a primitive knowledge of calc and physics thanks to easy level courses in first year. Anyway, because I won't be able to make changes to my schedule soon I really want to make sure I'm on the right track. I was...

Hi. I'm a second year student attending Universty of Toronto. In my first year, I took the very basic math courses and sciences. This includes PHY110Y and MAT135. The main reason for this is because I lacked any physics or algebra in highscool (I did have calculus) and was not permitted to...

So, I just finished up first FIRST YEAR of undergrad a bit ago, and am at somewhat of a crossroads Basically, I am leaning towards pure math, and was wondering how I could make myself more marketable "just in case". The pure math program is pretty flexible, and I can take a bunch of courses...

My first year of my physics/pre-med program is almost done (studying at UoWestern ontario.) I have heard some students say that they are going to pass on research so that they may take more courses to finish off their degree a year earlier(by taking 3 summers of courses to finish a 4 year...

What is covered in a typical first year undergrad calculus course? Is it just an in depth study of basic limits/integrals/derivatives? Or do they get into multiple integrals/vector calculus and stuff? Thanks.

How difficult is first year Calc-based physics?

Im having a bit of trouble on the last question of my assignment... The circular motion of a particle in the x-y plane is given by the equations: r(t) = 7.23 m, θ(t) = (6.33 rad/s)t, where r is the distance from the origin and θ is the polar angle measured counterclockwise from the positive...

how good an insulator is asbestos? (thermal conductivity 0.15 W/ m K). I am trying to determine the thickness of insulation required to reduce the heat loss of a spherical container by half. The answer I calculated it to be is 0.2cm which to me doesn't seem right (too small?) but having no...

Hello, I'm 25 and have been out of high school for about 6 years. Last month I started my first year in engineering after working as an electrical apprentice and I'm already falling behind in my math and physics courses. I've had one test in math and failed it and I have my first physics test...

Physics assignment due tomorrow morning... a few questions. 1. At a time when mining asteroids has become feasible, astronauts have connected a line between their 3500kg space tug and a 6200kg asteroid. Using their ship's engine, they pull on the asteroid with a force of 490N. Initially the...

Okay, in just a few weeks I start my first year at Malaspina Univsersity-College. I'm moving into a room in about a week or so that's just 2 blocks from the school (it takes more time to reach my buildings from the cafeteria than it does to reach the cafeteria from my apartment). So, could all...

This is my second day in physics class and we have merely learned the principles of displacement and velocity. I am having trouble using these principles in the problem which follows... Runner A is initially 10.0 mi west of a flagpole and is running with a constant velocity of 8.0 mi/h due...

HYE,CAN anyone give me an idea for first year engineering research project.

Does anyone have any first year mechanical engineering past exam-papers that I can have to use for my revision?

Someone said my first year doesn't even count towards my degree. Does this mean that I only have to pass this year (not with flying colours)?

Greetings all. Being a new member, I thought I would introduce myself. The screenname I use is my real name. I'm 18 years old, soon to be 19. I am currently in my first year of physics/mathematics at the Free University of Brussels. I was wondering who else browses these forums. It would...

Alright, so, let's say I decide to major in philosophy and possibly double major, or at least minor, in some social science (psychology, anthropology, ect.), what would I be required to take my first year? Not classes that have to do with my major, just other classes. Are there certain classes I...
