    Stiffness

    Assume a beam with attached rollers (top beam, see attachment) is being supported by another beam that is simply supported (bottom beam). I want to ensure the top beam does not get overstressed due to bending because the bottom beam is not stiff enough. Is it enough to assume that the EI value...

    Need help selecting an electric motor

    Hello, I have no experience working with electric motors, and I need some help selecting a motor to meet my requirements. Any help would be greatly appreciated. See the attached JPEG for my simplified setup. Requirements: The motor must pull the load at a constant designated velocity of 100...

    Fastener Loading question

    I have two bolts mounting a member to a fixed support (pictured in gray), where my load P is known. I'd like to use an "overhanging load" scenario where R_1 and R_ledge are my two reaction loads, except I have that 2nd bolt R_2 which complicates this a bit. I would assume that R_2 is going to be...

    Flat Rectangular Plates. Roarks

    I have a steel weldment with a wide top plate that will need to bear some significant load, F. Not sure if I'm okay to calculate my max stress as a simply supported beam, or if I should use Roark's formulas to calculate as a flat rectangular plate (although I would assume the latter). My a/b =...

    Bonded Standoff in Aerospace application

    Hello, Does anyone have any experience using Click Bond products? I'm trying to find info for CB3201 (standoff, locking thread, very large base). For spec sheet go to: http://www.enfasco.com/clickbond/PDF/cb3201.pdf I'll be using these standoffs along with p-clamps to support cables in a...

    Simplify combined loading case?

    What's the best way to go about determining shear and tensile loads in two bolts of diameter D that fix the two segments together -- where I have known forces and moments acting in the X, Y and Z planes (all with different magnitudes). Is there a way to simplify this? Thanks
