Want this question answered?
If five different forces are acting upon an object, it is still possible for the net force on the object to be zero. One configuration is forces acting in the form of a regular pentagon, the components of each cancelling each other out
Yes. Just take the vector sum of the first four forces (which can be anything), and make the fifth force equal to the negative of this sum.
Forces are derived from the first derivative of energy. The five forces are: F=[d/dr,del][Es,Ev] = [dEs/dr -Del.Ev, dEv/dr + Del Es + DelxEv]. There are two scalar forces and three vector forces as shown above. Forces and energy are quaternions, consisting of a scalar and three vectors.
Technically, all things that occur in nature are a result of forces. The most basic are the four forces that affect space-time, they are: gravity, weak force, strong force, and the electromagnetic force. Not too long ago we used to consider them as five because the electromagnetic force was understood to be two separate forces, the electrical force and the magnetic force. Today they are combined into one. The hope of physics is to unite them all into one force and this was called, in Einstein's time, the Unified Field Theory.

Sure. -- Three forces all pointing north, each of them = 10 pounds. -- Two forces both pointing south, each one = 15 pounds. or -- One 10-pound force pointing north, one east, one west. (Three forces.) -- Two forces both pointing south, each = 5 pounds. There are an infinite number of ways to arrange five forces with the same or different magnitudes, in different directions such that their vector sum is zero.

The five forces of Fenghao might include the two rivers that cross this city. Fenghao is a city in China that forms the capitals of Feng and Hao. There do not seem to be other forces in this city.
