This problem is problem 3.73 of the 8th edtion of this book. There are solutions from a previous version floating around but those are incorrect. The answer to this problem is Fv = 2011 lbf and x prime is 1.553 ft. Please help I have spent hours trying to figure this problem out. Thanks.
Liquid concrete is poured into the form (R=2 ft). The form is w = 15 ft wide normal to the diagram. Compute the magnitude of the vertical force exerted on the form by the concrete, and specify its line of action.
