How would I analize a bolt in tension and shear. Imagine an "L" bracket bolted in the configuration below "||" represents a bolt. There is a force "<--" at the top of the bracket.

The bolt will see tension and shear. There will be tension in the y direction (Sigma...
Imagine you have a cylindrical plug of plastic that you press fit into a hole. I need to determine the raidal pressure, radial stress, that the plug exerts on the wall of the cylinder.
Here is what I have so far.
Lateral Strain = (d_initial - d_final) / d_initial\
From what I...
From what I remember about momentum conservation is conserved in both x and y directions. Energy must be conserved as well (elastic collision)
If I have a cue ball moving to the right with velocity of 4 m/s and it hits another stationary cue ball with equal mass. The first cue ball is...
If I am at rest and I observe a train moving past me at .9c and then the train fires a projectile at .5c relative to it how fast do I observe the projectile moving?
With the speeds given, the lorentz factor is 2.294. I made the incorrect assumtion that I could just take the .5c and divide it...
Hi everyone. I've been out of college for some time and forgot how to determine the shape of a droplet. I know how to determine the contact angle based on the interracial energies of three mediums, but I'm not sure how to calculate the actual shape of the hanging drop. In my scenario I have a...
Keep in mind that when doing a fluid dynamics problem not all classical physics apply. I can see two reason why you observed what you did. The ball rising in the water will reach a terminal velocity very quickly, probably within about two feet or so. This would mean that past a certain depth...
I am looking to measure raw power input, but I have no way of measuring instantaneous velocity, only average velocity for each rotation of the chain, which is not a good enough resolution since the power will vary significantly within one rotation of the chain.
Correct, but since the velocity of the chain is due to the input force, shouldn't the peaks in the Power vs. Time plot coincide with the peaks in the force input? What this would mean is that the Power vs. Time would look identical to the Force vs. Time plot except it would be shifted...
That is where I am having difficulty. Let me know if you think this idea is valid...
If I know the length of the chain and how the tension force in the chain varies with time, then I should be able to calculate the...?Average?...power done for each cycle of the chain revolution. And then by...
Hello everyone,
I am currently working on a project where I am trying to find power by being able to measure the force as a function of time within a chain system, similar to a bicycle. If I know the force in the chain and how it varies with time I would be able to determine the impulse the...
Hello all,
I was wondering if there was a way to calculate the reflectivity of differing wavelengths of light hitting an element based upon its physical properties. I know that it is based on how the atoms of the material are excited based upon the wavelength hitting it. I eventually want to...
