To see how the speed of a wave on a string depends on the tension and the linear density, consider a pulse sent down a taut string (Figure 16.4.1 16.4. 1 ). When the taut string is at rest at the equilibrium position, the tension in the string FT F T is constant. Consider a small element of the string with a mass equal to Δm = μΔx Δ m = μ ...

This geometry produces two "null points" where the cantilever is tangent to the groove. At those points HTA is zero (note: the longer the tone arm's effective length, the smaller the offset angle. A smaller offset angle produces less skating. That is one of the advantages of a longer tone arm). Now look at the long and short green radii.
