EML3011C Mechanics and Materials I - Learning Objectives
These learning objectives were created to clearly state the skills that you are expected to master in this course.
By the end of this course you are expected to be able to:
- Units: Define the following terms (as numbers/values, or in mks, English,
or cgs units) force, pressure, stress, strain.
- Vectors: resolve vectors into components and perform vector addition, scalar
product (dot product) and vector product (cross product).
- Force Equilibrium: draw Free Body Diagrams (FBDs) for rigid bodies, beams,
2-D and 3-D structures, frames and machines, and set up equilibrium equations
(forces and couples) for them.
- Calculate the center of mass for a collection of particles and objects,
and also the centroid and moment of inertia for 2-D and 3-D structures.
- Determine and draw diagrams for internal forces and bending moments (axial
forces, shear forces, moments and torques) in a structural member.
- Understand the concept of stress and strain (true stress and true strain),
shear and normal components of strain and their relation to deformation vectors
and displacements.
- Understand the structure of metals, and how deformation is linked to dislocations
- Understand the stress-strain behavior for both ductile and brittle materials,
identify the following quantities on a stress-strain curve: elastic modulus,
yield stress, ultimate tensile strength, ductility, and toughness.
- Determine the deformations and/or normal stress in a member due to application
of forces and/or change in temperature.
- Analyze a statistically indeterminate structure.
- Analyze and design circular members in torsion
- Determine the maximum elastic internal bending moment for a beam.
- Determine longitudinal stress and hoop stress for a thin walled pressure vessel.
- Calculate stresses in a member subjected to combined loading.
- Find stresses and strains on arbitrary planes using transformations and
Mohr's Circle.
