Paper format. PEO/Engineers Canada National Examination 07-Mec-A5 Electrical & Electronics Engineering, May 2015 — 3 hours, closed book, Casio or Sharp approved calculator only. Eight questions of equal value; any five constitute a complete paper. All eight are solved here, since the set is intended as a study resource.

Constants printed on the front page. $\pi = 3.14159$, $1\ \text{hp} = 746\ \text{W}$, and the permeability of free space $\mu_0 = 4\pi \times 10^{-7}\ \text{H}\,\text{m}^{-1}$.

Reference texts for this subject.

Check — printed constants, checked against the printed paper. All three constants in Note [8] of this examination paper are printed correctly and are used exactly as given: $\pi = 3.14159$, $1\ \text{hp} = 746\ \text{W}$ and $\mu_0 = 4\pi \times 10^{-7}\ \text{H}\,\text{m}^{-1}$. The flux-path lengths in the Question 4 specification table are likewise printed correctly as $3.77 \times 10^{-2}$ m and $7.54 \times 10^{-2}$ m, and the negative exponents are used as printed; with them the reluctances come out to exactly $1.5 \times 10^{6}$ and $3.0 \times 10^{6}$ A/Wb, which is how the question was designed.
