EQUATIONS OF MOTION:
CYLINDRICAL COORDINATES
This approach to solving problems has
some
external similarity
to the normal &
tangential method just studied.
However,
the path may be more complex or the
problem may have other attributes that
make it desirable to use cylindrical
coordinates.
Equilibrium equations or “Equations of Motion” in cylindrical
coordinates (using
r,
θ
, and z coordinates) may be expressed in
scalar form as:
∑
F
r
= ma
r
= m(r – r
θ
2
)
∑
F
θ
= ma
θ
= m(r
θ
+ 2r
θ
)
∑
F
z
= ma
z
= mz
