It's time for another physics example. In this case, I am going to calculate the electric field due to an electric charged rod. Of course you could do this analytically using a bit of calculus. This ...

Whipping stress, caused by movement of rod around the crank centerline, produces forces which tend to distort the rod, as shown here by the dotted lines. At top dead center of the non-power stroke, ...

The traditional method for determining yield stress on a rotational rheometer or viscometer was by fitting models to the measured rheograms and extrapolating to zero shear rate. This article discusses ...
