If a body is subjected to stresses in xy plane with stresses of 60N/mm² and 80N/mm² acting along x and y axes respectively. Also the shear stress acting is 20N/mm². Find the minimum normal stress.
(a) 45.4
(b) 47.6
(c) 48.2
(d) 50.6
I am struggling with this question from in a case study.
The query is from the Principal Stresses & Theories of Elastic Failure unit in part Design Against Static Load of Machine Design
