WebFour-Bar Linkages #aml. A planar four-bar linkage consists of four rigid rods in the plane connected by pin joints. We call the rods: Ground link g g: fixed to anchor pivots A A and B B. Input link a a: driven by input angle α α. … WebIn fluid mechanics, the Rayleigh number ( Ra, after Lord Rayleigh [1]) for a fluid is a dimensionless number associated with buoyancy -driven flow, also known as free (or natural) convection. [2] [3] [4] It characterises the fluid's flow regime: [5] a value in a certain lower range denotes laminar flow; a value in a higher range, turbulent flow.
