Pull apart telescoping tube assembly

[swertel]

I'm looking for the value, but preferably the reference, to determine the force needed in the following scenerio.
Cross-posted from Human Factor/Ergonomics forum because I haven't got an answer there yet and I really want a MIL-Spec.
---------------------

I have an above average male (95%tile) holding a telescoping tube assembly in front of his chest. The assembly is parrallel to the floor. The male is holding the tube on the top, with palms facing down. His hands are spaced approximately shoulder width apart.

How much force can this male excert in trying to seperate the two tubes?

A MIL-Spec would be best, but any commercial/industrial standard will suffice.

Thanks,

Didn't see anything specifically applicable here, but it's something...

DEF STAN on HFE part 3 talks about strength, only as applicable to military activities.

Search "Human Engineering" on the Assist site... don't know which particular one has the information you need, but it's a place to start.

The motion you describe is like a reverse-fly in weight-lifting, so there may be some information to be found there.

I guess the NIOSH lifting manual would not help you, but as a initial guess 25lbs. Do an experiment yourself with fly fishing leaders as they come as low as two pounds tensile strength and go up in tensile strength.
