We thus see that the connecting pin moves 3 inches + 0·3811 inch while the crank is moving from the top to front centre. It will also move the same distance while the crank moves from front to bottom centre.
When the crank is moving from the bottom to the back centre, the connecting pin will move 3 inches − 0·3811.
