Description This subject deals with the action and interaction of forces, moments and couples in two and three dimensions. It examines the equilibrium of single bodies, and of trusses and mechanisms. It then looks at the friction between bodies. It covers the dynamics of a non-rotating body, and a body rotating about a fixed axis. Finally, internal loadings are investigated - particularly within a transversely loaded beam. The subject makes extensive use of vector algebra.

## Learning Outcomes

On successful completion of this subject, students should be able to:

1. Manipulate vectors in 2 dimensions and 3 dimensions.
2. Use the equilibrium equations to evaluate unknown reactions and internal loads.
3. Evaluate the member forces in planar trusses.
4. Evaluate the inter-body forces in planar mechanisms.
5. Calculate the acceleration of a body under the action of an unbalanced force or couple.
6. Analyse static and kinetic friction.
7. Construct bending moment and shear force diagrams.
8. Replace a distributed force by a single equivalent force.
9. Identify under-constrained and statically indeterminate problems.
10. Take measurements in the real world and use them to verify the theory presented in the lectures.
