Solved 3-3 A 1/2-in.-diameter structural steel rod was
Question: 3-3 A 1/2-in.-diameter structural steel rod was loaded in tension to fracture. The 8.00-in. gage length of the rod was marked off in 1.00-in. lengths before loading. After the rod broke, the strain in the 2.00-in. length containing the fracture was found to be 0.450 in./in., and the total elongation of the other 6 in. was found to be ...

Patella Fractures Treatment & Management
A case-control study by Liu et al (N = 90; minimum follow-up, 2 y) compared the clinical outcomes of three techniques for the treatment of transverse patella fractures: K-wire with tension band (KTB; n = 30), cannulated-screw tension band (CSTB; n = 30), and ring-pin tension band (RPTB; n = 30). CSTB was found to be superior to KTB and …
