    Math required for nuclear engineering?

    As an engineer of any type, you can almost be guaranteed that almost every one of your technical classes will be mathematically based. Some more than others, but you will definitely be exposed to mathematics from day 1 to day n.

    Programs Is a Double Major in Economics and Mathematics Worth It?

    one semester will be a tiny blip of time 5 years from now. A tiny blip for a double major? go for it.

    Need to Purchase a Universal Testing Machine

    Thanks for the reply CalcNerd. The intent of purchasing the universal testing machine would be to measure the compressive and tensile strength of the different materials. We currently have standards and equipment already in place to test finish, colour, and other quality characteristics.

    Need to Purchase a Universal Testing Machine

    Hey all, I have been put in charge of developing my company's research and development "lab" and I am currently looking for some testing equipment to buy. My background is in civil engineering, however I did do a small amount of material testing in school, and I'm familiar with the concepts...

    How to calculate indoor temperature?

    R-2.0 seems very low for an insulating material. How thick would it be? I could easily run a quick 2D thermal model for you.

    Understanding Thermal Properties of Materials: A Comprehensive Guide

    VIP panels are also pretty neat. Very high R-Value, and can be easier to work with than aerogels depending on the application. I'm thinking of fiber suspended aerogels.

    Understanding Thermal Properties of Materials: A Comprehensive Guide

    Physior, I think the majority of your concerns can be solved looking at the materials thermal conductivity. The thermal conductivity is basically a materials ability to transfer heat through conduction, or the transfer of heat through a material. You may have heard this referred to as a...

    Shear Failure of Adhered Polystyrene (to Aluminum)

    ahh this makes sense. Rather then calculating the shear stress in the foam, I calculated the force exerted to the aluminum layer BY the resistance of thermal expansion of the foam. I have found an article which I am looking into...

    Shear Failure of Adhered Polystyrene (to Aluminum)

    Thermal stress (σ) created by thermal expansion resistance will be calculated using the following formula: σ=E∙α∙dT Where: σ= Thermal Stress (kPa) E= Youngs Modulus (GPa) α= Thermal Expansion Coefficient (m/(m℃)) dT= Temperature Differential (℃) The thermal stress (σ) value will...

    Shear Failure of Adhered Polystyrene (to Aluminum)

    Hi All, So here's the problem. A project I am working on has a composite metal panel assembly, which a previous engineer designed. The metal panels are simply glued to the polystyrene (styrofoam sm). The problem is that the previous engineer did not consider the difference in thermal...

    Dual Skin Facade Design: Advantages & Challenges

    No offense taken Danger. This is what I created this thread for. First of all, I am not denying that both methods you mentioned are feasible solutions for energy savings, I think it comes down to the desired applications. I need to look more into the methods you mentioned in order to be...

    Dual Skin Facade Design: Advantages & Challenges

    Hey All, Im creating this thread to share some of the information, and hopefully gain some information on dual skin walls. Dual skin walls are a fairly new advancement in facade design in North America, however they are more common in Europe. The first dual skin facade in North America...

    Structural Connection Design (Metal to PVC)

    OK here is an updated drawing of what is actually happening. This is an overhead view of an aluminum curtain wall (window) frame. The blue is aluminum. The PVC adapter is being screwed into the aluminum through one wall via access holes. The composite panel bracket is being screwed into the...
