—!how heavy a single bit of string is. Linear Mass Density μ
The linear mass density (μ) of a string is a measure of the
string’s “heaviness”. Thicker ropes have a higher linear
mass density than thinner ropes. Steel cables have a
higher linear mass density than nylon climbing ropes. etc.
If you know the linear mass density, and you know how
long your piece of rope is (L), then you know the mass of
that piece of rope: m = μL.
When you cut up a rope, you change the mass of the
pi...
