is the magnitude of a 3D vector Q 5i - 3j + 7k. By equating to zero the coefficients of the unit vectors in each of the two relations (see the above equation), we obtain the desired scalar equations. Equilibrium of the system is achieved when the net force acting on the system is zero i.e. In statics, we consider the forces acting on the object as a whole and. A body is an object, possibly made up of many parts, which may be examined as a unit. We observe that as many as three unknown reaction components may be eliminated from these computations through a judicious choice of the point ‘O’. Engineering statics is the study of rigid bodies in equilibrium so it’s appropriate to begin by defining what we mean by rigid bodies and what we mean by equilibrium. Next, we compute all vector products, either by direct calculation or using determinants. We write and express the forces ‘F’ and position vectors ‘r’ regarding scalar components and unit vectors.

The force in the pole acts along the axis of the pole. These equations can be solved for no more than six unknowns, which generally will represent reactions at supports or connections.ĭuring solving the most of the problems, the above scalar equations will be more conveniently obtained if we first expressed in vector form the conditions for the equilibrium of the rigid body considered.
