In a four linkages slider mechanism shown in Figure 2, when the crank turn the connecting rod responsible to rising and lowering a weight that riding against incline plane. When the connecting rod lifting the weight, it has to overcome the gravity and the friction force between the weight and the incline plane. On other hand when the connecting rod lowering the weight the friction force will reduces the force on the connecting rod. Therefore the loading on the connecting rod is fluctuating from 9kN to 2 kN. Find a factor of safety of connecting rod against fatigue for infinite life using Goodman theory. Check the first cycle yield factor of safety. The connecting rod is made of AISI1018 CD? A reliability of 90% is desired.
