    Monorail Crane Beam Bolted Connection to Side of Header Beam

    I'm designing a monorail beam for a monorail crane. Crane capacity is 5T, span between supports is 25'. I've spec'd a W14x61 beam. Originally, the beam was to be mounted on top of header beams at each end. Unfortunately, these header beams are already in place and are too high for the...

    Converting kinetic energy into a force

    Hi, I'm currently designing some end stops for a crane, and it has me thinking about some pretty basic questions that you guys may be able to help me with. I know that the energy that the crane's bumpers absorb is based on the kinetic energy of the crane as it hits the end stop. I know that...

    Program to Calculate Ellipse Aspect Ratio

    "I" have to write the program to do this because the aspect ratio is only one part of the analysis that we are performing. I now have a program that will read in a data set and spit out a series of different usefull characteristics that i can use to track different trends. Thanks for the help...

    Program to Calculate Ellipse Aspect Ratio

    RWF7437 - I'm not sure if you are trying to point me in the direction, or simply shame me. But in either case, yes, i read the wikipedia antry for ellipse before posting this question. Right now i'm thinking that the best way to go about this program would be to tilt the ellipse so that the...

    Program to Calculate Ellipse Aspect Ratio

    I am working with a large data set of vertical and horizontal velocities. When I plot these velocities, they form an ellipse. I am required to write a program that will determine the b/a ratio of these ellipses. It will be easy to determine the length of the major axis... simply the...

    Need a list of sound speeds for MANY fluids.

    So my boss is looking for a dictionary, or some sort of listing that will have the sound speed for lots of fluids. The more the better. I'm having no luck finding such a thing. I know that sound speed can be calculated from density, and the density of many fluids is easy to find, but we're...
