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.
