between 4 r and 5 r; i.e., - = 4 r to 5. The usual ratio is 4.5 but in naval engines where height is of importance a ratio of 4 is used.

The effect of thisangularity is to increase the load W to the following extent:F = Wk.I If = 4 4-25 4-5 4-75 k = 1.033 I-03 1.026 1.023 1.021W = maximum load upon piston rod. The diameter of the rod at mid-length can be…
