The rotating parts of the thigh occur at the hips and the knees for which some type of bearing is required to enable smooth movement. For simplicity this would be a plain bearing (bushing), press fitted into the hole as the load is light with a small degree of movement and low rotating...

It is possible to do a roll-out test while lightly scooting along while bearing weight on the handlebars and one foot on a pedal, but it's better to have an assistant holding the bicycle upright and pushing it along. You may use the valve stem as a reference, starting the roll with ...
A bearing housing for a two-wheel air cycle machine includes a first housing portion, a second housing portion, a third housing portion, and a journal bearing bore. The first housing portion is centered around an axis and has a first side and a second side. The second side is positioned ...

It was found on a general basis that Series 2 has higher load-bearing capacity and limited deflection. Series 1, which has a higher density, was able to absorb more impact energy but was more susceptible to damage. A Life Cycle Assessment (LCA) was conducted to evaluate the environmental ...
Since data on rutting accumulation were collected from accelerated pavement testing, the number of wheel passes required to accumulate a 12.5-mm (0.5-in.) rutting was extrapolated for this analysis and converted to equivalent single-axle loads (ESALs). The extrapolation was based on a piecewise ...
The cycle wheel is actually a gear with 65 teeth. Rather than ball bearings a plain bearing (bushing), is created using a brass tube and rod. Cut a 3.5(dia)mm tube to a length of >8mm and round the outer edge with a file. Place the wheel on a firm flat surface with the back ...
