I don't have any kind of numbers, facts or figures on me, but I am a material engineer. Generally, whenever a material is hardened, it becomes more brittle in a sense. It doesn't mean that it becomes brittle, but the material loses its ductility. That is the reason for say annealing. It...
After doing some research, I have come to the conclusion that if i neglect torque, then I don't even need to worry about moment of inertia. Is this correct? I can't find any equation that relates linear motion with moment of inertia unless there is torque involved.
Is this correct?
I have a Force Acceleration analysis that I am un sure of. I have a picture of a skull that is punched/kicked/whatever in the chin.
Problem Statement:
The head shown in the figure below is considered a rigid body. IT rocks on the occipital condyle, C, where an axial force, Fa, and a...

Try that file. Those are notes from an automotive class being offered at my university. I can't tell you how long those will be up so you may want to save them.
Hope this helps.
Since it is a train, it should be the same principles used on cars.
The aerodynamics should be very very close if not identical.

LC is lift due to canard
LW is lift due to wing
Alpha is the angle of attack for the wing.
aw is lift curve slope of the wing
hn is the distance to the neutral point
hcg is the distance to center of gravity
I believe you are right on the moment arms being the l's.
CMcg is...
I'm in an aerodynamics class, and I have this canard configuration I'm trying to figure out for a final exam.
I need to find the sum of the moment about the center of gravity.
I may cannot be helped without the drawing being posted.
So far this is what i have:
Mcg = Mac - (lcg + lw)Lw +...
So am I to assume that the pressure needed to propel the ice a certain velocity cannot be solved theoretically without taking a long time to do?
My professor wants me to do it, but I don't know if it can be done. I have talked to 2 other professors who haven't lead me in the right direction...
This isn't a homework question; however, it is probably similar to one.
I am doing a design project that involves a hail cannon. Basically I have created an air gun that propels ice balls.
I have a compressed air tank, with an electronic quick release valve and then a barrel made of PVC...
I have some aerodynamics homework to finish up, and I am not really sure how to do one part.
Question is: What is the corresponding zero Mach number lift coefficient
I can't find an equation in my book or anything. Can someone maybe shed some light?
My first two questions were to...
I need help with 2 questions that I can't seem to figure out. I had them for homework but I never got it right and the homework has since been turned in.
I was told I would most likely see these problems again on the exam. Therefore I need to learn how to do them. Can anyone help me out on...
I am having difficulty with this homework question. I am not even sure whether to start.
Question:
A molecule of DNA lies along a straight line. It is 1.061 micrometers long. The ends of the molecule become singly ionized; negative on one end, positive on the other. The helical...
I realize I made the description kinda worried.
Basically I have a 3" diameter barrel, connected to a 1" Quick Release Valve, that's connected to a 2" expansion chamber which is connected to an air regulator and on the other side of the regulator is where the air hose will be connected...
