11 Template for how the questions wills be organized

This “textbook” is a work in progress.

This is a template for how we will proceed.

This is how you, the student, should organize your solutions, in particular when you hand in homework.

Special thanks to Peter Mulhern from the University of the Fraser Valley for this template.

The template for all of these questions, and solutions will be as follows.

Solution

Statement of intent:  One or two sentences that clearly state how the solution is being started and organized.  If you are talking to another student and telling them how to solve the problem, you do not start with an equation.  “Vomiting equations onto a piece of paper” is not a solution. Communication is an important part of being an engineer,  You need to establish confidence that your approach is valid.

Text of the solution

Clear free-body diagram or FBD from now on.

The final answer will be in a text box with an arrow to the far right where the variable is repeated,

Sample problem

A car starts from rest and uniformly accelerates at 2.00 m/s² to the right in a straight line.   How far does the car travel in 5.00 seconds?

Statement of intent:  What principle is being used? This is a constant acceleration problem, so I will start using the standard equations of kinematics.

x = vt + ¹/₂ at²

x = (0 m/s)(5.00 s) + (1/2)(2.00 m/s²) (5.00 s)²

The final solution will be in a text box and use a full sentence or table.

For example

The images come in four levels.

“minimal or quick level sketches”, notebook sketch level.  ( 5 minute sketch)

“detailed notebook sketch”, (15 minutes sketch, highlighting critical areas)

The idea is to move to good mechanical drawings, “presentation level”

and then some general public “artistic drawings”.  This is a work in progress.
