Hi anybody got a copy of Christopher Kitcher Practicle Guide to Inspection and testing and certification

Why well I tried to do Test 1 on App C P179 and found (so far ) 2 claring typos that does not instill me with confidance.
First question 3 4 double sockets on a 4mm radial calculate the r1 +r2 at each socket but if you check the answers on p210 gives the answers for 3 sockets instead of 4.

Second question 5 is a 4mm ring at 87 metres but the answer has the cable at 67 metre ?

Anybody else spotted this because I am starting doubt this book and does not help the novice starting out anyway
 
Hiya Pal,

I've got the book, and yes there are mistakes in the book.
All I can say in the way of encouragement is that you've 'found' the mistakes.

As long as you know how to work them out then you're fine. It's always best to try to work them out for yourself and then check the answers - that way you find such mistakes, instead of getting confused.

All the best with your studies.

Steve
