The equilibrium conditions of statics state that a body at rest remains at rest if the sum of all forces and moments acting on that body is zero. Determining the forces and moments is the basis for the design and dimensioning of structures and components. Example: A block on an inclined plane. A simple free body diagram, shown above, of a block on a ramp illustrates this. All external supports and structures have been replaced by the forces they generate. These include: mg: the product of the mass of the block and the constant of gravitation acceleration: its weight. N: the normal force of the ramp. Sum of all forces acting on block will be mg Since component of mg along the inclined plane is mgsin (theta) and normal force should be equal to mg cos (theta) Fww = mgcos (theta)
