    Static Calculation of Guardrails

    Hi JStephen, Thanks for the reply. For this case, I already look into the energy methods, but to simplify the calculation, I've decided to not use it since the acceleration does not give much impact. What i am looking for is the force required to rotate it. Meaning that the force required to...

    Static Calculation of Guardrails

    Hi everyone, I've been tasked to calculate the force required to push a set of guardrails using a pneumatic cylinder. The objective is to reduce the weight of the guardrails and hence, reducing the force resulting lower force required to rotate the pole of the guardrail from zero degree to 90...
