I have defined an RPM on a shaft and assigned a loading function with time - basically for the 1st 10 seconds it does nothing and then it kicks in. However the shaft begins to rotate (in oppsosite direction) as soon as the solution starts - see images below. Force graph should be zero between 0-10 seconds but it shows load.
Have I defined something wrong?
Unfortunatly not, I ran the same simulation with zero loading with time for the entire time stamp - zero load as expected:
However, I think I found the fix. I had truncated the loading curve - Thinking the software could interpret the remaining data. Ie Loading was defined as so:
but if I define each time step I get the following:
Suppose that's what assuming does!
