The objective in presenting this unit is to provide students with detailed knowledge of the fundamental principles and applications of structural mechanics and static engineering.

The subject matter covered in this unit will include: the equilibrium of rigid bodies subjected to dry friction; rolling resistance; analysis of pin-jointed trusses using the method of joints and the method of sections; shear force and bending moment diagrams for beams; kinematics of particles; analysis of the motion of particles and rigid bodies using Newton’s laws; and, work, energy, impulse, and momentum as applied to particles, systems of particles, and rigid bodies.

The unit provides experience in design for axial loads and direct shear and determining shear stress in simple beams. We also cover determining torsional stresses and strains in circular shafts and determining beam bending stresses and strains.

At the conclusion of this unit, students will have the requisite knowledge to analyse and solve rigid body and kinematics problems in a multitude of settings and have the ability to transfer this knowledge to real world applications.
