(20%) A point in a structure sees the following stresses σx= 10 ksi, σy = 15 ksi, σz = -5 ksi. What are the associated strains εx, εy, εz, knowing the modulus of elasticity is 20ksi and Poisson’s ratio is 0.3. If for a different point in the same structure with the same material, the strains are εx= 0.001, εy =  εz = 0, what are the σx, σy, σz stresses at that point?

  During the last 2 months, your department has compared 94 internal carotid arteries evaluated by carotid duplex with angiography. The results showed 50 vessels had a hemodynamically significant lesion by either method. 40 vessels had no lesion by either method. In 1 case, the noninvasive ultrasound was negative, but the angiogram showed a 70-99% diameter reduction.  In 3 cases, the noninvasive studies were consistent with a >50% diameter reduction, but the invasive study was read as normal. What is the negative predictive value?

Popliteal Artery Entrapment Syndrome is common.
