Ahip joint replacement must withstand large forces. if you stand on one leg, the load exerted on the hip joint is 2.4 times of the body weight. assuming a simple cylindrical model for the implant, calculate the corresponding stress (in mpa) on a hip implant with the weight of 200 lb. the hip implant has a cross-sectional area of 5.3 cm2. if the hip implant is made of ti6al4v (124 gpa elastic modulus), what is the strain for the given loading conditions? if the hip implant is made of 316l stainless steel (190 gpa elastic modulus), what is the stain for the given loading conditions? compared these two materials, which one will be better used for the implant and why?

A41-year-old man comes to the clinic complaining of a chronic cough over the past 4 months, which has now been accompanied by haemoptysis. he denies smoking or any past medical history. on physical examination, his head and neck examination is normal. his lungs have diffuse bilateral rales. cardiac examination is normal. laboratory findings reveal na 142 meq/l, k 4.2 meq/l, cl 110 meq/l, hco3 24 meq/l, bun (blood urea nitrogen) 39 mg/dl, creatinine 2.9 mg/dl. urinalysis reveals microscopic haematuria and 4+ proteinuria. which of the following serologic blood tests would most confirm the suspected diagnosis? - anti-glomerular basement membrane antibodies- anti-mitochondrial antibodies- anti-neutrophilic antibodies- anti-parietal cell antibodies- anti-smooth muscle antibodies
