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 $0\mathrm{.}5$ 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
