One of my fellow undergraduates is currently working with Idaho National Laboratory (INL) on a project having to do with developing nuclear power for space
Everyone,
I am a Mechanical Engineer working on a design modification (or existing product recommendation) for an Idaho National Laboratory project.
What follows is the situation description. At the end is the question. You can skip down to the bottom of the post (which details the...
There I edited my original post. So far as a picture... I wish I could, but I don't know how. Any suggestions? I could find a similar picture and try to cut and paste it into a post.
I have a simple statics problem that I am trying to solve. The rigid body to be analyzed is an upside down L-shaped beam connected together at the corner by a pin. The object has a height of 4.5 meters vertically, by 3.5 meters in the horizontal. Additionally, the object is secured to the ground...
Need Solutions Manual for "Mechanics of Materials"
I am trying to locate someone that has a solutions manual for "Mechanics of Materials" Edition 4 by Beer, Johnston and Dewolf...copyright about 2005. If anyone has one or happens to know where to get one or where to look I would be...
EXACTLY WHAT I WAS THINKING... now I feel better that somebody else was thinking that it didn't make sense. I wish my teacher would proof homework before he gives it out to students.
Thanks for all your help.
(KE)im1=(KE)fm1+(KE)fm2--->
masses cancel out and 2*m*(.5) cancels out to give the following
(((3Vi)^2)/2)=(.5*(sqrt5Vi)^2)+Velocity^2[<---velocity for mass 2]
3vi^2=9vi^2,---->sqrt5Vi^2=5Vi^2, so---> Taking .5*sqrt5Vi^2 to the other side...
You said find the initial angular momentum and then find the final angular speed, but I thought that it gives you the final angular speed of 3.54rps. Maybe I am totally confused though.
here is what I did, but my answer is all messed up. I got 13.73 meters as my radius for my masses. Here...
I have a question about this question that I hope someone can answer.
QUESTION: "A student on a piano stool rotates freely with an angular speed of 29.5rps. The student holds a 1.25 kg mass in each outstretched arm, .759m from the axis of rotation. The combined moment of Inertia of the...
I have a problem here. I got "answers", but I don't believe they are correct and I have no idea where I went wrong.
The question is... "Determine the speed V_2 (V sub 2) of the larger mass after the collision and Theta 1 and Theta 2.
mass of smaller particle = m
mass of larger particle =...
Slope of an x vs t plot question...Help please..
The slope of an x vs t plot is NOT acceleration right? The slope of a point on the x axes is just the velocity at that point in time, right? Thanks for any help you can give me.
There is no mistake in your reasoning. The key point to note here is that the two definitions of Galois extensions are equivalent only in the case of finite extensions. In your example, the extension field K of \mathbb{Q} is infinite, and hence the two definitions do not necessarily hold.
To...
It is possible that you have misunderstood the definitions of the two properties. Let's review them in more detail:
1. A Galois extension is a field extension L/K where L is a splitting field of a polynomial over K and every automorphism of L that fixes K is a K-automorphism.
2. A Galois...
Yes, this functional equation does have a solution. In order to find the solution, we need to determine the functions r(x) and h(y) that are being added together inside the function g. Once we have these functions, we can plug them into the equation and find a unique solution for f(x,y). So, the...
Your thinking is correct, the set of all nonnegative integers is not a field. In order for a set to be a field, it must satisfy certain properties such as closure under addition and multiplication, existence of additive and multiplicative inverses, and commutativity and associativity of...
