g A steel [E = 26800 ksi and α = 7.1 × 10-6/°F] rod containing a turnbuckle has its ends attached to rigid walls. During the summer when the temperature is 93°F, the turnbuckle is tightened to produce a stress in the rod of 4.3 ksi. Determine the stress σwinter in the rod when the temperature is 21°F.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

The characteristic roots of a dynamic system are: 1.7920 1.8160 i, -1.7920 1.8160 i, -0.4160 what is the order of this system? what are the settling time and damping ratio of the system?

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false
