How do the roller coasters hold in people in the loops, using mathematics equations and explanations?

The centripetal force supplies the necessary forces to hold a person in. The harness restraints act as a backup.

A highly simplified equation is:

F(net) = ma = F(support) + F(gravitational),

but this is different for each position of the roller coaster. Since the coaster is an extended object and not a point, the math exceeds that which is taught in high schools.
