As kinetic energy K=12∑i=mqidq˙i/dt, then it is clear that the first term in the brackets is ∂K/∂ξ˙j and the second term is ∂K/∂ξj. Thus: (1.17)ddt∂K∂ξj−∂K∂ξj+∂U∂ξj=0 This is a more general form of the Lagrange’s equation than (...
This three-dimensional distribution of the fluid density can be resolved by recording with the optical setup several projections in different directions through the flow and processing the obtained data with the methods of computer tomography. If the flow has rotational symmetry, one projection only ...
Recently I was searching the internet and books for the connection between conservation of angular momentum and conservation of rotational energy and found nothing. Let's say an ice skater rotates and draws the arms in - the rotation speeds up. The rotational energy must increase because the......
