OH! That makes complete sense. Okay so now for Tau, the two formulas I'm looking at are Tau=(VQ/IT) but now what is Q and I? and for the Torsion portion to add to the first tau, would I do Tau=(TR)/J, so R is radius, t is torque=15,000, what is J? Thanks a bunch BTW, You're helping out in a...

So mass has nothing to do with I. Would the I in this case be I=(Pi*r^4)/4? If so my stress is close to the answer. I get 82,760 when the answer is 84,670. What about Tau? Where Tau=V*Q/Ib. Or would I use a different formula to find Tau since this is a Cylinder?

So should my M diagram look more like: and how do I figure out the moment of inertia without a mass?

draw it all out, and measure the resultant. the distance you measured is the resultant. ie, if F=80n and it's 8cm long, that's 10n/cm. You draw it all out to scale, measure the resultant. and 10n/cm*R= Resultant force.

Graphically. Use a ruler and find out how long they are. Graphical method is proportionate.

no. Excuse the crude use of mspaint. It'll look like: technically you don't need the Left E vector and top F vector. You see how I just moved the E vector over to the F vector? and drew the resultant from beginning to E's tip.

Move the point at which the e vector begins and put it at the end of the arrow of the F vector. Draw a line from the point the F vector begins to the end of the arrow on the E vector. Put a nice little Arrow at the end of the line you just drew by the end of the E vector, and that is your...

I should know how to do this because I know I've learned it a year ago. This is just a refresher homework assignment and for the life of me I can't remember how to do this. In the attachments, I'm including the problem, the questions, as well as my attempts, which are likely, very wrong. Any...

I've done Physics with Calculus for Engineers 1-3. I'm also currently working on the basic engineering courses(Statics, Dynamics, Fluids etc).

Hello, My name's Konrad (don't let the username fool you! haha). I'm currently a junior in Aeronautical Engineering (Embry-Riddle Aeronautical University) with a minor in Air Traffic Management. I was planning on just ending school with a Bachelors and going right out to work. However, I've...
