I've attached a problem from the testmasters geotech review... I am completely stuck and I have lost a section of the geotech notes that would have covered pile capacity problems. CERM doesn't seem to approach them the same way and I cannot find a similiar problem. If anyone knows how to tackle this or has the testmasters explanation notes for this section and can help I would be VERY thankful. Even if you don't have the testmasters but know how to solve it PLEASE tell me!! I have no idea where the 30 is coming from in the first calculation
