I've been working on Ex 5.4 in MTW. The maths is fairly straight forward, but I don't really understand what is going on!(adsbygoogle = window.adsbygoogle || []).push({});

In part (b) what are the 'forces' pushing the volume through a distance? If they are forces, they must produce an acceleration but we have a constant velocity. Are these forces producing the stress in the volume?

What would be an example of a 'stressed' medium as used in this example?

If m^{jk}is 'inertial mass per unit volume' equation 5.51 will sum to produce the total momentum in the direction of v, not one of the components.

Can anyone shed any light?
