A 55-year-old female was admitted to the hospital due to “pounding” in her chest, nausea, and diaphoresis (sweating) that persisted for 40 minutes after a routine jog. The heart rate was 65 beats per minute, and the blood pressure 138/72 mm Hg. Doctors noted that her blood troponin I level was elevated and continued to rise 11 hours later (from 0.055 ng/ml to 0.415 ng/ml; normal range, 0 to 0.045). All other tests were normal with the left ventricular end-diastole pressure, 5 mmHg, and she was discharged with aspirin and a beta-blocker for presumed exercise-related supraventricular tachycardia. Four months later, while she was on a downhill-skiing trip in Vermont, she experienced acute nausea and emesis (vomiting) followed by chest pain and dyspnea (difficulty breathing). The heart rate was 111 beats per minute, the blood pressure was 115/81 mm Hg, the troponin I level was 11 ng/ml, and the white-cell count was 36,100 per cubic millimeter (normal range, 4500 to 11,000). Intravenous infusions of heparin and furosemide (diuretics) were administered at a local emergency department then transferred to the local hospital via helicopter. On the patient’s arrival, the heart rate was 143 beats per minute, the blood pressure was 96/72 mm Hg, and the troponin I level was 4.790 ng/ml (normal range,

A shаft shоwn is mаde frоm аn aluminum tube (shear mоdulus 27 GPa), which is bonded to a brass core (shear modulus 45 GPa). The length of the shaft is 1 m. The shaft is clamped at B and a torque T is applied at the free end A. The allowable shear stresses in aluminum and brass are 100 MPa and 120 MPa, respectively. The radius of the brass core is 25 mm, and the outer radius of the aluminum tube is 50 mm. Determine the maximum torque T can be applied at the free end. Please enter the maximum torque value in the box below.
