In this paper the problem on “Magnetic fluid lubrication of porous-pivoted slider bearing with slip velocity by N Ahmad et.al.[7]” has been recapitulated using Jenkin’s model [4] with the additional effect of squeeze velocity of the above plate. It is found that while discussing the above problem, [7] has stated but ignored the term , where +, in their study (Refer equation(2.2)). This paper re...

Microball bearings can potentially provide robust and low friction support in micromachines such as micromotors and microgenerators. Their microtribological behavior needs to be investigated for design and control of such micromachines. In this paper a vision-based, non-intrusive measurement method is presented for characterization of friction in linear microball bearings. Infrared imaging is u...

Injuries to the posterior cruciate ligament (PCL) commonly result from frontal automobile crashes when the occupant’s tibia interacts with the intruding knee bolster of the vehicle. The goal of this research study was to better understand injury to the PCL due to this impact scenario and correlate injury with the response of the knee slider of today’s crash test dummies. Over a span of two year...
