External and internal forces. There are TWO types of forces that designers MUST consider when designing structures. External Forces: forces that act on a structure from the OUTSIDE Internal Forces: forces that act a structure from WITHIN. External forces.
POINT OF APPLICATION:
The precise point at which the force is applied
PLANE OF APPLICATION:
An imaginary flat surface through which an applied force passes
****the point and plane of application make a difference in how an applied force affects a structure. See page 278 in your text
The force acting within the rope is called?
shear torsion tension compression
