determine the grain size using the following equation n100=nM M = M 100 2 Real length Scale bar (written dimension)

If ß-Sn, a tetragonal crystal (point group 4/mmm, a = 0.583 nm, and c = 0.318 nm) is subject to a tensile stress of 63 MPa along [100] and to a shear stress of 18 MPa on the (100) plane in the [010] direction. Determine: a) the tensile stress normal to (110), and b) the shear stress on the (110) plane in the [1-10] direction.

SECTION B- STRUCTURES-DR LARISA MALYSHEVA QB1 DIRECT STRESS Two round solid bars of different materials are connected (in parallel) and have a common tensile force, P, of 190 kN is applied,ras shown in Figure QB1. For each bar, determine the: a) b) Stress. Strain and Strain in the diameter. Use the following information. Clearly show all your derivations.
