Consider the infinitesimal stress cube under loads, in kpsi, taken at a point in a body. a) (10%) Determine all the Cartesian stress components. b) (5%) Assume that your answer to part (a) were kpsi 10 kpsi 10 = = = = = = zx yz xy z y x Determine the maximum shear stress. Q.4. (30%) The hollow round frame, made of a ductile material with MPa 100 = y S , is subjected to an end torque of 600 N-m as shown. If the outer diameter is 20 t , determine the thickness t based on a factor safety of 1.25 and the MSS theory. Round-up your answers to the nearest integer in millimeters. 600 N-m t x y z 7 9 5 30 ° shear 8 shear 45 ° 20 N/mm 150 mm 300 mm P = 10 MPa 7...
