Applied Definition and 1000 Threads

I'm having a bit of a dilemna. I'm currently a senior in Mechanical Engineering and will finish in about 1.5 years. I always feel that ME alone might not be as useful and wish to expand my knowledge in Physics or Mathematics. I'm equally passionate of both, and have thought about minoring in one...

Compute the maximum longitudinal force that may be supported by a bone before breaking, given that the compressive stress at which bone breaks is 2.00e8 N/m^2. Treat the bone as a solid cylinder of radius 1.55 cm. The attempt at a solution I tried using the equation Max Torque = pi/4 * (r^3) *...

I have to do a calculus project by researching somewhere it's applied and writing about it and explaining it thoroughly. I was thinking multivariable calculus / vector calculus was used in satellite orbit math, but I could not find enough on this. Any ideas on where else it's applied that...

Hello, I'm an undergraduate who's going to be a senior this coming fall. I'm currently triple majoring in Mathematics/Engineering Physics/Biological Engineering. I'm also looking to enter graduate school in applied mathematics. My schedule for this last year all fits together quite well, except...

Hi Physicsforum, I'll be graduating next semester (one semester early) with a degree in Pure Math and Statistics (minor in Atmopheric Science). I have good research experience and an internship and can get some good letters of recommendation. However, I'm worried that I don't have enough...

"A 50 kg crate is being dragged across a floor by a force of 225 N at an angle of 40° from the horizontal. The crate is dragged a distance of 5.0 m and the frictional force is 60 N." Now from that information i am supposed to find the work done by the applied force on the object. This is...

In a place with no friction, I have a rocket that applies a constant force f to a weight of mass m, and between them is a spring with constant k. I assume that the mass of the spring is negligible. As the three objects accelerate, by how much does the spring contract? My intuition tells me...

I'm surprised that I didn't find this topic in any other threads on here so I'll bring it up. I'm finishing my MS in Applied Physics, paid for by my employer. Now I have some choices; I could apply to a PhD program (given my interests probably NE), I could apply to a MBA program, or I could...

I am currently in school for an undergrad degree in Mechanical Engineering with a concentration in aerospace (i.e. Aerodynamics instead of fluid dynamics, propulsion instead of applied thermo, and some aerospace electives). I have hopes after to work for an aviation company such as Boeing...

Good afternoon! I will begin taking upper division mathematics in the fall, and I definitely wish to obtain a Master's right after undergrad, and as for PhD, I'm a bit iffy if I want one (I'll save that for another post in a couple years ^.^) Anyway, I have 4 electives where I get to choose what...

Ginsparg "Applied Conformal Field Theory" I have some questions concerning the first two chapters of Ginsparg's text on CFT, which can be found here 1. In equation (2.1) primary fields of conformal weight (h,\overline{h}) are introduced as fields that transform the following way...

I'm just starting out right now as a math and chemistry major. Should I choose applied or pure math as my concentration? I've been told that applied math will help me with chem, and I agree. However, I also feel comfortable with the theoretical side of things, and it's a large part of what draws...

Hello everyone, I'm new to PF. (My favorite fish is herring, so slap away. :smile:) My question might be a bit complicated, because I suspect the answer depends a lot on location. I live in the Netherlands, and that's where I'm going to uni in september. (Rijksuniversiteit Groningen, RuG) I'm...

I am starting graduate school in applied math in the fall and am trying to decide if measure theory is necessary or important in terms of applied math and if so, what ares of applied math? I have taken two basic real analysis courses through multiple integrals, etc. and would like to focus on...

Hey guys, I have a simple conceptual question: Let's say I'm moving a loop of wire into a constant magnetic field that points into the page. The wire needs to create a magnetic field out of the page to oppose this previous change in flux. The typical question would be which direction does the...

Hi. I am a math major that got started late. I started taking prerequisites during my sophomore year (which I'm finishing this year). I'll be taking some courses in algebra and analysis next year. There are some courses that can fulfill my major requirements, but some are theoretical and some...

Let's say that a ship makes small jumps in speed with a momentum measured by the ship observers as p each time. The first jump from the rest frame brings them to a speed of v. They continue to do this n times, so the the total momentum applied locally according to them is n * p, right? After n...
