Subject Title

Subject Description


This course introduces the subject of statics. The study of particles and rigid bodies in equilibrium. The students study, and solve problems involving, the equilibrium of particles and rigid bodies in two and in three dimensions. In particular, they calculate the forces in the members of trusses and frames. They also learn to calculate the coordinates of the centroids of two-dimensional geometric figures as well as the centre of gravity of homogeneous solid bodies. Problems involving machines and equilibrium problems which include dry friction are studied as well.

Learning Outcomes
Upon successful completion of this subject the student will be able to:

Upon successful completion of this subject the student will be able to:

1. Calculate the resultant of a number of concurrent forces in two or three dimensions.

2. Calculate the magnitude and direction of a force required to keep a given force system in equilibrium.

3. Draw a free-body diagram of a particle acted on by forces and use the diagram as an aid to calculate the magnitudes and directions of the unknown force(s) if equilibrium is to be obtained.

4. Use the concepts of moments and couples to calculate the single force and the single couple which is equivalent to a system of coplanar couples and/or non-concurrent forces.

5. Define a rigid body and use free body diagrams to aid in solving for the unknown forces and/or couples required to maintain a two dimensional rigid body in equilibrium. 

6. Calculate the coordinates of the centroids of plane areas and of the centers of gravity of homogeneous plates having uniform thickness. Calculate the magnitude and locate the line of action of that single force which is equivalent to a distributed load using the concept of the centroid of area.

7. Calculate the magnitudes of the unknown forces acting in some or all of the members of a truss, machine or frame which is acted on by a number of external forces and /or couples and which is in equilibrium.

8. Explain dry friction and use the equations of dry friction to solve the problems of statics equilibrium.

Academic Integrity
Seneca upholds a learning community that values academic integrity, honesty, fairness, trust, respect, responsibility and courage. These values enhance Seneca's commitment to deliver high-quality education and teaching excellence, while supporting a positive learning environment. Ensure that you are aware of Seneca's Academic Integrity Policy which can be found at: Review section 2 of the policy for details regarding approaches to supporting integrity. Section 2.3 and Appendix B of the policy describe various sanctions that can be applied, if there is suspected academic misconduct (e.g., contract cheating, cheating, falsification, impersonation or plagiarism).

Please visit the Academic Integrity website to understand and learn more about how to prepare and submit work so that it supports academic integrity, and to avoid academic misconduct.

All students and employees have the right to study and work in an environment that is free from discrimination and/or harassment. Language or activities that defeat this objective violate the College Policy on Discrimination/Harassment and shall not be tolerated.
