Problem 5, Part 4 You are looking for bearings that are suitable for the shaft a at location B. You desire shaft a to rotate at 3,000 rotations per minute for 45,000 hours. The below bearing information is for a component that is believed to be appropriate. What is the dynamic load rating for your application? As part of your submitted work you must explain whether or not this component would be suitable for the design.
Read DetailsA patient with cardiogenic shock is experiencing symptomatic bradycardia. The nurse administers the prescribed dose of atropine, but the patient’s heart rate does not improve. Based on this assessment, which provider order should the nurse anticipate next?
Read DetailsFor Part 3, assume stress concentrations are present. Notch sensitivity for the bending stress is q = 0.85. Notch sensitivity for the torsional stress is qs = 0.8. Continue to apply a safety factor of 3. In the detailed design for the system, the gear on shaft a actually rests against a shoulder to the left of the gear. The gear has a width of 1.5 inches and sharp corners are assumed at the shoulder Problem 5, Part 3a What is the dynamic stress concentration factor at the shoulder? Please use the conservative estimate from the table for finding stress concentration factors.
