Hey guys, I'm stuck on this equation never done anything like it but apparently its due to come up on exam next week. Any ideas on where to go with it so far...i stopped as i was about to remove the integral for U1 as it is constant.
As concerns the second part, I'm I right in presuming i work out the thickness, fill that into the given u equation and then in turn use the derived equation to solve

Hope ye can help, thanks.

The reason you're not getting any responses is because of the poor quality of the figures you have provided. No one is going to take the time to try to read them, especially the ones that are rotated 90 degrees.
