Question
Design of machine elements
A britle material has the properties Sut = 30 kpsi and Suc = 90 kpsi. Using the coulomb mohr and modified mohr theories , Determine thefactor or safety for the following states of plane stresses.
a) σx = 25 kpsi σy =15 kpsi
b) σx = 15 kpsi σy = – 15 kpsi
c) σx = 20kpsiτxy= -10 kpsi
d) σx = – 15 kpsi σy =10 kpsi τxy= -15 kpsi
e) σx = – 20 kpsi σy =- 20 kpsi τxy= -15 kpsi
