Here you go, Piston area and force.

OK,
I apologise for using the word dummies.

Fair enough

This 'discussion' started because 273 claimed that more piston area gave more hp by virtue of the piston area increase.

Never did, your inferring that, I've larger piston gives more force to the rod and crank for a given cylinder pressure (efficiency)

Bewy said
It only does this IF more air is drawn into the cyl; if no more air was drawn into the cyl, then the HP would not change, all else being equal.

Again were talking force and torque, no time frame (rpm) is be discussed.

The only time I've mention hp as in where talking similar hp and torque so were comparing apples to apples.

THIS FORMULA SPECIFICALLY ADDRESSES EXACTLY WHAT IS BEING DISCUSSED. What do you not understand about Power per piston area???

Again were talking piston area and it's effect on force to the crank.

How does does say 2 vs 4 hp per square inch of piston area have anything really to do with force the piston is applying to the crank ?
