Vector diagrams are used to resolve (break down) a single force into two forces acting at right angles to each other. A free body diagram models the forces acting on an object. The object or 'body ...

Resultant force = 4 + 3 = 7 N to the right In the ... The sum of these two forces can be found using a vector diagram. The two forces are represented by the adjacent sides of a parallelogram ...

The free-body diagram method is emphasized. Topics include vector algebra, force, moment of force, couples, static equilibrium of rigid bodies, trusses, friction, properties of areas, shear and moment ...

These diagrams are curves in which the radius vector represents in magnitude and ... of the horizontal component of the earth's magnetic force at any particular station.
