    Wind turbine blade characteristics

    I'll get a chance to see the tunnel some time soon and then I can better answer those questions. Regards, Kane

    Wind turbine blade characteristics

    I'm about to start a project in which I want to study the effects of making modifications to a wind turbine blade. I am going to be able to use various external flow modeling software our aerospace labs. I am a mechanical engineer and am used to using solidworks and I understand that that can be...

    Designing Coaxial Output Shafts: Fatigue Analysis

    I think I am going to chase down the derivation of the goodman equation and find where they insert the diameter cross section and then plug in my hollow shaft cross sectional area and find it that way. thanks

    Designing Coaxial Output Shafts: Fatigue Analysis

    Part of my design project requires that I design two coaxial output shafts. I've gone through and calculated the inner shaft based on deflection and Goodman fatigue criterion. The problem now is this: the other output shaft must be a hollow shaft that shares its axis with the interior shaft. All...

    Flywheel Troubles: Designing an Energy Storage System for a Small Buggy

    If you want to take this that seriously you are going to need to lay out a design that you can draw dimensions from and then work gear ratios. To make this a conceptual head problem would cause me problems for sure.

    Mechanical Engineering Streeses

    think about the neutral axis and which side is in tension/compression then use the stress equation for a beam in symmetric (assuming) bending. simple. but I've done it a few times.

    Understanding Strain Invariants in Strength of Materials

    Can anyone help me understand the concept of a "strain invariant" given a strain state matrix? or perhaps point me towards something? thanks for any help.

    What is the direction of the buoyancy force?

    i believe the buoyant force acts upward through the COG of the displaced volume.
