The torque you reckon? Which is the force translated to the fly wheel?
By lever arm do you mean the rod length? or the distance from the pin on the fly wheel to the fly wheel centre?
Done a free body.
I can't think of what the y force would be? there should be none on the piston (other than gravity and some force N pushing up on the piston but since there is no friction i ignore these right?)
Though there will be an x and y component of the forces on the pin at the other...
Given that I have a steam engine, and now its size, the size of the piston, the length of its stroke and the force acting on the piston at certain points, I need to calculate the force on the crankshaft.
Now, I now that Fx should be the same where the piston meets the crank, and we can ignore...
