MATLAB Tutorial
MATLAB is an extremely useful tool that can be used to calculate the transformation matrices or
to check your work. We encourage you to use MATLAB to solve problems in ME 347! It is
very fast to do for 3-D problems and can save you so much

3-D Geometric Transformation Example in MATLAB
A cube with length 1 undergoes geometric transformation in 3-D. The initial position of the
cube is shown below. The cube is first rotated +90o about the x-axis and then +90o about the ya

ME 347: Homework 1
You are tasked with designing a simple cell phone stand for a company. The client has asked it to be
universal so that it can fit any phone with maximum dimensions of 6.5x3.25x0.5. They would also
like it to have a cut at the center of

ME 347: Homework 4
You are designing a new fusion of pliers and forceps. Ultimately the client wants the comfort and
strength of the handles of pliers with the accuracy and precision of curved forceps. Pictures are seen
below. The forceps should curve at

ME 347: Homework 2
You are designing a wall mounted coat rack for your new home. The wall already has 4 pre-existing
holes which you can screw into. Each hole is horizontally spaced 1 foot apart and allows for a 1/4"-20
ANSI standard screw. You want to be
