CONCLUSION
It can observed from the above analysis that Maximum value of equivalent stress is there in Cast steel : 160.52 MPa while least in Cast Bronze 64 Mpa.
Total deformation is same in all the cases.
Stress intensity is maximum in Cast steel and it\'s value is 176.04MPa. while least in Cast bronze: 71 MPa.
So considering above factors CAST Bronze should be recommended.
