Propranolol (Kd= 0.005 µM) is an epinephrine (β-adrenergic) receptor antagonist. Which statement best describes epinephrine (Kd= 5 µM) signaling in the presence of propranolol? A) Propranolol will bind the receptor with higher affinity and mimic epinephrine B) Propranolol will bind the receptor with higher affinity and block epinephrine C) Epinephrine will bind the receptor with higher affinity and signaling will continue as normal D) Propranolol and epinephrine will bind at different sites on the receptor and signaling will be blocked

The shaft shown below is made from 1040 steel with properties of Sy = 71 ksi and Sut = 85 ksi with dimensions given, and the journal bearings at A & B prevent motion of the shaft but do not create reaction moments. Forces F1 = [F1]0 lbf and F2 = [F2]0 lbf are applied in the vertical direction to the shaft as it rotates. Determine the minimum diameter needed for the shaft so that it will last an estimated N = [N],000 cycles before fatigue failure. Use an endurance limit of Se = 40 ksi.Hint: The critical location will be at bearing B.Enter your answer in units of inches and rounded to 3 decimal places. Write down all your work to scan and submit. L1 = [L1] inch, L2 = [L2] inch, L3 = [L3] inch
