Instructions (optional)A connecting rod turned by the crank is responsible for raising and lowering the weight riding against an inclined weight. It is found that there are 4 kip: tensile load in the connecting rod when it is lifting the weight and 0.5 kips tensile load when it is lowering the weight. The connecting road is made of 1018 cold-drawn steel, and the surface is unmodified. The required rellability is 90%. Find the factor of safety against fatigue assuming infinite life and using the Goodman criteria. Also, find the factor of safety against first-cycle yielding
