    FEA use nowadays

    You definitely don't want to be the "FEA guy" in some companies. Running a "quick" FEA on an item to make sure it will handle 3x the load it was initially designed for because sales can say whatever they want to close the deal.

    New job and lack of mentorship.

    It sounds like management will boot him before he can get up to speed. "You're an engineer you should be able to control the weather right?" Sincerely Greedy Moron

    How to get non-engineers to understand what an engineer knows?

    At least you have the chance to influence the design. I've worked with techs/fabricators who would make products and then use engineering to create drawings and models from the completed part. Of course, if a problem surfaced with the part, engineering was questioned on our design decisions...

    Indirect load sensing

    I have been asked to monitor load induced pressure in a double acting cylinder using a pressure transducer or switch. This is intended to automate a process control or I would use a pressure gauge. I realize this is not as straightforward as load cells but I would like to use an existing...

    UV stabilized plastic reccomendation

    So TiO2 is used as a UV stabilizer? One material manufacturer said it was an antioxidant and didn't specifically serve as a UV blocker. My thermoformer thinks the Marine board will form the same as regular HDPE.

    UV stabilized plastic reccomendation

    I have found a UV resistant HDPE called Marine Board. Would it have the same processing capacbilitites as a standard HDPE?

    UV stabilized plastic reccomendation

    Thanks for the replies. Does white PVC have better UV properties than a white PP or HDPE?

    UV stabilized plastic reccomendation

    I have a thermoformed HDPE cover that is used outdoors as a machine guard. After a few months in service the part becomes brittle and fails. Can anyone reccomend a material that has similar mechanical poperties with enhanced UV stability? The color must be white or a carbon black would be...

    LRFD for safety handrail

    OSHA calls for a SF of 4 on platform components. The guardrails are 200 lbs for the top rail as mentioned above. The spec. only states the rail should support this weight without failure.

    2 switch control circuit

    That right. Its not foolproof. The operators manually extend the outriggers using the control valve and use visual feedback to determine sufficient contact. The trucks are rated to be stable on slight inclines. So I could use a displacement sensor to trip the relay at a voltage corresponding to...

    2 switch control circuit

    This is for outriggers on an aerial lift truck. Where the pressure is measured it will spike when the cylinders contact the ground but will drain off due to the valve characteristics.

    2 switch control circuit

    The output would likely be 0-10V DC.

    2 switch control circuit

    Thanks for the help. It turns out where the pressure is sensed it will peak and then drain off. So i will need some sort or latching/holding method. Alternatively I am looking at displacement sensors in the cylinders. Is there a type of relay with adjustable latching voltage that would match...
