    FE method, how ? (software Comsol)

    No, the Gauss points are no the mesh nodes. The Gauss Points, or Gaussian Integration Points, are internal to the elements. More can be found here (last paragraph of the page marked 11) and here.

    Sphere slipping against block

    Hmmm, maybe I'm not understanding the problem correctly, but the geometry for this problem seems to be over-constrained. From the problem statement: The distance from the center of the sphere to the contact point on block B (or A for that matter) is (√R)/2. We'll call this B. The...

    Focusing on a specific area of Mechanical Engineering Undergrad?

    Is there more information you can provide on this research opportunity focusing in fastening and joining (ex: what type of joining)? Of the given choices, automotive structures is the most applicable; you'll want to focus in structural analysis.

    Stimulating Airbags

    SolidWorks mostly likely cannot (depending on what you want to simulate). If you want to simulate an airbag deploying, then you'd need a code that can do highly non-linear dynamics, such as LS-DYNA (Abaqus and MSC can do it as well, but probably not as well as LS-DYNA).

    Force on Boom Arm due to suctioning sludge

    This is a simple fluids and statics problem. You'll first need to figure out you mass flow through the boom arm and the area of the inlet; you can use these values to calculate the force at the inlet of the boom. You'll then apply a force and moment balance at the outlet end of the boom (where...

    Help with Integrals (one of which involves erfc).

    By garbage I mean that the plot doesn't make any physical sense (both in temperature values and distribution). Mathmatica does appear to evaluate the erf(x) correctly.

    Help with Integrals (one of which involves erfc).

    fi(τ)=hT∞ I did state that, but it was after the final solution I got (my mistake for stating it so late).

    Help with Integrals (one of which involves erfc).

    I'm using Green's Functions for heat conduction problems, and I'm trying to solve the following integral: Homework Statement http://img28.imageshack.us/img28/4923/026307b169b04faa8364086.png [Broken] Where: http://img820.imageshack.us/img820/3742/6332938c445f4b9e8da8ba5.png [Broken]...

    Can DOUBLE SHEAR occur in ANY direction?

    Think of a material element in the pin and using the reaction load son the pin to find the principle stress.

    Screw and mating thread strength equations

    In addition to the friction between the mating threads (which you accounted for), you need to account for the friction between the head of the bolt and whatever surface it is coming in contact with.

    How can a hydraulic steering be replaces the modern power steering system

    May I ask why you're set on having a pure hydraulic steering system?

    How to make gear?

    You can scribe a gear (straight cut teeth) on a piece of brass. Use a hacksaw to cut off the bulk of the material, a drill to bore out the shaft hole, and then a file to shave everything down to the final shape. Very time consuming, but it will work non the less.

    Scissor mechanism: static analysis

    Maybe I'm not understanding you mechanism correctly, but if the spring only supports a compression/tension load and is always in the center of the two cross bars, then the load in the spring will be exactly the same as the vertical load applied at the top (assuming no friction). All horizontal...
