Amount of Force Generated

  1. Nov 13, 2015 #1
    I have a rod which is rotating at 100 rpm I want to understand what amount of force it applies on square plate with thickness of 1 in, and length and breadth 1 in.

    There is no way to know based on the information provided. Even if you knew, what use would that information be?

    The amount for force required to stop a rod which is rotating at 100 rpm will depend on the size and shape of the rod, its mass, its mass distribution, the direction in which it is rotating, the distance from its axis where the force is applied, the angle at which it is applied and the length of time for which it is applied. That's assuming a constant force -- which this will not be.

    Let me put it this way... I have a square plate which needs to be hit/clicked certain number of times(which is 100 times per minute) to do a desired action say A.. I have this rod which is rotating at 100 rpm.. Action A can occur only when enough force or pressure is applied on the square plate. The way of applying this pressure is from the rotating rod which will have a protuding head which will come in contact with the plate and hit the plate at 100 RPM or 100 times/minute. I want to understand what pressure or force its generating on the square plate.

    Depends on the details of the collision of the plate and the rod.

    Thank you jbriggs444 thats what I am trying to figure out what equation would that be derived from...

    The details of the collision will depend on the design of the machine you have that makes the rod collide with the plate. It is not clear that the relevant measure of the result is force. I suspect that impulse is the more relevant quantity. But in addition to not knowing much about the collision, we have not been told anything about the sensor.
