These two totals are the x and y-components of the resultant vector. The moment of a force F about an axis through a point o is defined as the product of the magnitude of F times the perpendicular distance d from the line of action of F and the axis o. Moving a force from A to B, when both points are on the vector’s line of action, does not change the external effect. Magnitude of a Vector: Direction Cosines: Cos(a), Cos(b), Cos(g) Unit vector along a vector: The unit vector u A along the vector A is obtained from. This may be a bit more work than to calculate the resultant using the Law of Cosines and the Law of Sines as was done in the preceding section. It therefore describes the procedures to find the magnitude, direction, and the line of action of the resultant force to keep this system in equilibrium. Replace this force system by an equivalent resultant force and couple moment acting at point O. 1 - Moment of a Force (scalar) 4.

(Of course, if the body is in equilibrium then there is no resultant - it should be zero. The resultant is determined by summing all forces in the. CoG thru 3D Rigid Bodies: Lectures 29-36 Determine the magnitude of the resultant hydrostatic force acting on the gate AB. The sum would be the resultant vector connecting the tail of the first vector to the head of the last. The tendency of a force to make a rigid body rotate is measured by the moment of that force about an axis. For instance, 5 m/s Eastward is a velocity because it tells you the magnitude of the movement, 5 meters per second, as well as the direction which is Eastward.
