... October, 1990 and the vehicle was serviced a day before (i.e. 22nd October, 1990). During this service, the wheels were rotated and the bolts were tightened using the manufacturer's wrench. All tyres were in new condition. A speedometer reading was of 76376 kilometer at the time of accident. The right...

.... Corrective Measures To minimize the possibility of a recurrence of this type of failure, the wheel nuts were tightened with an air-impact wrench to a torque of 610 to 678 J (450 to 500 ft · lb) dry. All wheel studs were checked at normal maintenance periods to ensure uniform and proper loading...

... information to an antenna and subsequently to an FM receiver-demodulator. The experimental setup was calibrated by putting one end of the drive shaft in a vice and applying 100 lbf torque to the other end. While the 100 lbf torque was applied, the output of the demodulator was measured with a voltmeter...
