An earth retaining structure is 12 feet high. The soil behind the earth retaining structure is a sand having a moist unit weight equal to 125 pcf, a saturated unit weight equal to 130 pcf, and a friction angle equal to 32 degrees. Determine the resultant lateral earth force and the location of the resultant force for the parameters,
