Plz help!! WILL MARK BRAINLIEST :) Which forces are easier to anticipate and
design for, internal or external? Why do
you think this is so?

The external forces such as wind, water and the vibration of the earth when an earthquake happens create internal forces within a structure. Internal forces such as shear, tension and compression can destroy the inner framework of a building or a bridge even though it is made of super strong steel and concrete.

I Hope This Will Help You ...
