! Required information Water (y = 62.4 lb/ft) is retained by a uniform thin semicircular dam having 1 ft radius and 3 ft depth into the plane of the figure. The dam weighs 60 lb and is supported by a cable AC and by frictional contact with the bottom of the channel at B. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 1 ft 1 ft A B 3 Determine the minimum coefficient of friction required so that the dam does not slip at B. (Round the final answer to four decimal places.) !
