1. Problem:

2. Problem:

Thank You Very Much!!!

Ex 6-1) Transform into principal stress Transform into max shear stress and associated normal stresses O -2 kgf/mm kgt/mm2 -4 kgf/mm2 O,4 Txy 5 Things to Remember Max normal stress o Min normal stress o2 No shear stress exists with either o1 or o2 (o o2/2 Radius Tmax Tmin Plane having max/min shear stress has normal stress of o (o1 o2/2 o,)/2 =(a. + If a o. Then Mohr circle- Point No shear stress can be made. 0, Mohr circle locates at the center and Pure shear exists. If o o = Pure shear > principal stress o1Txy O2 Ty acting at 45 deg to the direction of shear stress 01 02 Ox Oy O. constant + Tay-3 kgf/mm2 Ex 6-2) o, 2 kgf/mm2 o, 4 kgf/mm2 Calculate the principal stress and the maximum shear stress and plot the direction. Ex6-3) o, 80 kgf/mm2 o, 50 kgf/mm2 = 0 Ty Calculate principle stress and the maximum shear 50 and plot the direction. 80
