The aim of this assignment was to become familiar with the CAD environment of Siemens NX as this sofware was used in all other projects and assignments during the course. The objective was to develop a full 3D assembly and create accompanying technical drawings for one of four proposed objects. Students were required to develop their 3D models with as many details as they thought it would be necessery and select appropriate mates and material for each part. My choice fell on a TQ TM105 centrifugal force apparatus. All measurements were taken using a ruler and a vernier calliper. As this device was used by students during other courses in order to not damage anything I decided not to model the inside parts of it.

The aims of this assignment were to become familiar with conducting a Finite Element Analysis of a slender structural member using NX, implementing beam elements and 3D solid elements, as well as to understand mesh independency and how that affects the computational cost.
The assignment consisted of 5 main parts.
Part 1 was theoretical and contained 15 questions such as "What is the stiffness matrix of a beam?" and "What is the effect on the beam stiffeness if the modulus of elasticity increases?".
In part 2 students had to conduct analytical calculations of a beam for given material, dimensions, load, stress constraint and deflection constraint.
The beam used in part 2 was also used in part 3 to condcut Finite Element analyses using beam elements and in part 4 to conduct FE analysis using 3D solid elements. Students were required to develop a CAD model for the beam under the given loading, fully define all necessery properties and justify the selection of boundry conditions. In part 3 the FE analysis were conducted using 10, 20, 30, 40, 50 and 100 elements. In part 4 students were required to select 6 different element sizes and justify the selection.
Part 5 was focused on comparison between reseived results.

This assignment consisted of two tasks.
Task 1 was to analyse a two-link planar manipulator and first use MATLAB to reproduce graphs given in the coursework paper, and next use Siemens NX to simulate the manipulator, and then compare MATLAB results and NX results.
Task 2 was similiar to the first one, however in this case students had to analyse a four-bar planar mechanism.
