Earth Pressures - I have the solution but I cannot get there myself!
Hi All! How are we all today?
I have come across a math problem which I just cannot solve (even though I have the solution!). I can barely see my desk for the piles of attempts I have made at this on paper so I could really use your help! The problem and the answer are on the attachment. I think the problem I am having is with how to treat 'exp' in the question. I would really really really appreciate it if someone could show me the correct way to approach the problem. It could be as simple as me not using my calculator correctly!
Thank you all!
I forgot to show on the attached that B and tethe (sp?) are equal to zero degrees
