7.3.1 Strain Measurements In comparison to the dynamic component of the strain, the static componen be large enough to accommodate the full-load dynamic strain.h total measureme l

i SS-1 for example, the static component is less than 10 percent of the full In the case of load peak-to peak strain.
Nevertheless, the procedure described in.
Appendix A permitted the measurement of the static strain components to an accuracy of about 3-4 percent of the peak dynamic strain and, therefore, represents the limit of the total measurement accuracy achievable in this type of a test.
The dynamic strain is largest for 55-1 and $5-2.

h peak-to peak values vary almost peak-to-peak value varies from about 560 micro-strain at speed-no-loa about 1300 micro-strain at 3500 W.
h magnitude of S5-2 has been found to be on the same order as S5-1 and the measurements have b static and dynamic tests of both test series.

The waveforms of the strain, especially S5-1, are extremely steady and periodic.
They repeat every two revolutions of the crankshaft.
