The conversion factors for SI system are:
And for the English system are:
pounds per inch
In this module, the forces (elements Force, Friction or Resultant) are added to the objects (elements Block, Pulley, Spring and Point) placing the force in one of the cells around the object. Each object (if there isn’t in the chalkboard’s border) have 8 cells around it.
This module have 30 elements, presented below. With a description of each one, its data and its number of equations. Notice that some elements have one or two equations, depending of the applied forces. If all forces are horizontal, or vertical, the object have one equation, otherwise have two.
