Sorry, I used the wrong value for the angle in cosine. It should have been 155 and I used 160. This should be correct, the textbook I'm working from has the same as their answer. It could be wrong but I doubt it.
Here's the complete walkthrough of the problem...
Homework Statement
Determine resultanat force of vectors P (40N) and Q (60N). P is 20 degrees from reference plane and Q is 45 degrees from reference plane.
Homework Equations
When using the parallelogram rule, should you always start with the lowest angle vector? (like in the bottom...
If you were starting on the hill, yes the torque needed would be greater. If you have started before the hill, you would need to calculate the force to keep moving up the hill, which would obviously be smaller than starting from a stop on the hill. hope that helps
Create an experiment :-)
1) drop the ball from a known height
2) record the ball dropping using a camera horizontal to the ball and have some sort of visual reference in the background (like a pole with incremental, known heights)
3) record a few different heights and calculate the velocity...
Just a quick question about ANSYS. I'm thinking about taking FEA offered next year and was wondering how difficult it is to learn ANSYS. Anyone have any suggestions on books/references I could use as an aid with the class?
What program are you using? I would just suggest reading the manual for your respective program and trying to replicate what is in it. It worked for me with Pro/E.
Ya, it's the same project as before. This is pretty much what I need to figure out:
1) Velocity at end of manifold and end of tailpipe
2) Temperature at end of manifold. I'll assume this temperature throughout the exhaust because I am not going to use different materials from one end to...
You will see a decrease in fluid velocity. As for the laminar flow, it will be laminar but you will have separation points along the outside of the cube. As the fluid separates from the cube, it forms vortices between the laminar flow and the cube surface. Google flow visualization and look...
So, I'm still working on designing an exhaust. The engine I'm using is the VR6, non-turbo, etc. I want to design the exhaust only under full throttle. This way I can over-design the exhaust rather than under-designing it. I'm really not sure how to find the velocity of the exhaust as it...
Alright, I'm on to doing the thermodynamics portion of the project, starting with the cylinder head. I know I have to find the amount of gas injected into the cylinder. What should I learn to be able to find the force that combustion of the gas will give me? I'm just not really sure what...
That's not going to work. Just think for a moment about what you just posted about not being 100% efficient. If one fan is not 100% efficient, that means that as you propel the other fans with your one fan the amount of energy received at the end of your line of fans will not be equal to the...
