In worked example 1. Problem
The Attempt at a Solution
It's the part where I'm subtracting one stress from the other stress. I put it in parenthesis on the worked example. I don't think my method here is right, I've tried to subtract each like term from the other to get my B term. When I come to extract the 3.3/8 by 3.3/8 it should be 3.3/8 - (-3.3/8) giving + 3.3/8.
Also why is the radius term now divisible by the variables on the right?
Can anyone see what's going on here?
