What is Engineering design: Definition and 17 Discussions

The engineering design process is a common series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered - though the part(s) that get iterated and the number of such cycles in any given project may vary.
It is a decision making process (often iterative) in which the basic sciences, mathematics, and engineering sciences are applied to convert resources optimally to meet a stated objective. Among the fundamental elements of the design process are the establishment of objectives and criteria, synthesis, analysis, construction, testing and evaluation.

    I Uncovering the Forces on Drum Lugs: An Engineering Design Exploration

    I am currently designing an alternative to normal acoustic drum lugs and I need to find the forces that are felt by the tuning rods of a drum for the engineering background to my design. I have been able to use the 2D wave equation assuming uniform tension on the membrane and found values of the...

    Engineering Calculating valve sizes for a compressible liquid

    I have converted given pressures from bar gauge to bar abs Inlet pressure = 20 - 1.013 = 21.013 bar abs Outlet pressure = 6 + 1.013 = 7.013 bar abs therefore pressure drop (x) x = {p_1 -p_2 \over p_1 } = {21.013 - 7.013 \over 21.013} = 0.6662542236 bar abs Comparing to the chart values for...

    Constraint Programming(ish) For Engineering Design

    I've been working on a tool in a browser for engineering (particularly civil engineering) design. By design, I just mean finding values (maybe the cross-section or material of a beam) which satisfies constraints. You would define constraints, possibly have something to minimize or maximize (like...

    Possible Air Conditioning System?

    Hello everyone! Summer is coming and instead of buying a $200-$400 air conditioner, I'd figure I could try a DIY version. I came up with a schematic (attached below) and how I think it would work. I feel like I'm missing something blatantly obvious that will make it not feasible. Wondering if...

    Direct Stiffness Method for a distributed load

    I'm working on a question which asks to determine the deflection, curvature, forces and moments of a simply supported beam with a distributed load. diagram shown in here http://imgur.com/a/wpI4kInitially, I've done the calculation with 1 plane beam element with 2 nodes. At L = 0 and L = 3. But...

    Engineering Design: Truss Bridge Questions

    Hey. I am currently in an engineering class designing a truss bridge and had a couple questions. (Note all truss members are considered to be two-force members) 1) Suppose the truss is symmetric and a force is applied through the middle of it. Is it normal in industry for any individual...
