Unformatted text preview: M rectangle ( y =8 ft) = 671 ft 3 ] compared to the trapezoidal section [ M trapezoid (y=8 ft) = 500 ft 3 ]. Both curves have similar shape, but the trapezoidal curve is shifted upwards by approximately 1 to 1.5 feet. In other words, the two curves are roughly equivalent except that the trapezoidal curve needs 1 to 1.5 feet more of depth than the rectangular curve to obtain the same momentum value as the trapezoidal curve....
