The typical sign convention for a moment in 2-D is that counter-clockwise is considered positive. MOMENT OF A FORCE - SCALAR FORMULATION For example M O F d and the direction is counter-clockwise.

FERC Statics 7-5. Resultant of Spatial Concurrent Force System Spatial concurrent forces forces in 3-dimensional space meet at a common point but do not lie in a single plane. Sarah pulls on one end of a rope with a force of 100 N and her friend Jane pulls on the other end with a force of 100 N.

F F1 F2 F3 50 10 70 10 N. Resultant of a force system is a force or a couple that will have the same effect to the body both in translation and rotation if all the forces are removed and replaced by the resultant. Often it is easier to determine M O by using the components of F as shown.

F n Since we know that every force on the plane OXY can be decomposed depending on its cartesian axes then. Often more than two concurrent forces are to be added. The equivalent resultant force and couple moment acting at A.

If the lines of action of F 1 and F 2 are maintained then the resultant force P has the correct magnitude and direction but its line of action is not obtained because the line of action does not pass through the point of intersection O Figure 27d. Draw a vector diagram to find the resultant force. Two forces 300 N at 0 degrees and 400 N at 90 degrees pull on an object.

FERC Statics 7-4 Resultant Force. Here we make use of direction cosines andor unit vector to help define the exact direction of a force vector. 33 COPLANAR FORCE SYSTEMS This is an example of a 2-D or If a particle is subjected to a system of coplanar forces that lie in PROBLEM.

The analysis of such a system is demonstrated in the following examples. A 2-D force and couple system as shown. Using this approach M O F Y a F X b.

The equation involving the resultant of force system are the following R_x. Note the different signs on the terms. I Let us take Fy and Fz and find the resultant of these components using parallelogram law in YOZ plane.

Distance between F B and the axis of rotation r BC 20 cm 02 meters. 1 Sum all the x and y components of the forces to find F RA. One force has a magnitude of 10N and the other force has a magnitude of 8N.
