Question

13. A piston must fit in a bore with a diameter of 3.3750 in. What must be the diameter of the piston given the clearance shown in the diagram.

Answer 1

According to the graph, the distance between the diameter of both circles is 0.0025 inches.

To find the diameter of the piston, we have to subtract.

$3.3750^{\doubleprime}-0.0025^{\doubleprime}-0.0025^{\doubleprime}=3.37^{\doubleprime}$

As you can observe, the diameter of the piston must be 3.37 inches.
