I majored in electronics, not mechanical engineering, so I am a novice to measuring forces.
Finding out average man's arm strength can be done.
How do I measure the force on the handles? Can you suggest which measuring instrument to use?
In the image attached, you can see a hand operated plunger for making String hoppers. The handle is rotated and the screw descends and plunges into to canister containing the batter.
To mechanize this process, one can use a linear actuator, but the catch is estimating the linear force...
