Aim

To give a broad based introduction to mechanical engineering science.
Learning Outcome At the completion of the module the student should be able to:

· Draw shear force and bending moment diagrams for loaded beams, and calculate bending stress.
· Calculate shear stresses due to torsion, and thermal stresses
· Carry out calculations involving linear and rotational motion and apply those principles to simple mechanical systems.
States and uses Energy conservation equations
· Use steam tables to evaluate water properties
State and use the continuity equation

Solve problems involving forces exerted on mechanical elements due to fluid motion
Indicative Content Calculation of forces on beams dues to point and uniformly distributed loads. Calculation of bending moments, and the construction of shear force and bending moment diagrams. Determination of the position of the maximum bending moment. Definition of the centroid, and calculation of the position of the centroid for various sections. The relationship between bending moment, beam proportions and bending stress. Shear stress, shear strain and modulus of rigidity. Transmission of power in shafts and the calculation of the resulting shear stress. The coefficient of linear expansion, and stresses resulting from temperature gradients.

Moment of inertia and radius of gyration. Rotational dynamics. Centripetal force and acceleration. Power transmission using belt drives.

Energy conservation, the steady flow and non flow energy equations. Thermodynamic properties, using steam tables. Continuity, Bernoulli. Applying Newton`s laws of motion to fluid motion.
