Like the forces on a rotor blade in operation, centrifugal forces do
have some affect on things.......
It doesn't take much bend to have a terrible affect on a prop blade and
balance.

It takes a lot of force to permanently bend an aircraft propellor blade,
that is my point. Sure, a bend in the blade is very bad, but bending
the blade isn't easy and few people could do it by hand.
