Each row represents the distance from the center of the riser to <br />each strap. For calculation simplicity, fictitious straps were added at the left and right tank ends. <br />The last step of the tension riser calculation adds the tension of these fictitious straps to the first and <br />last anchor straps respectively. <br />Distance of Center of <br />Riser to Each Strap <br />distr'ijLrj La'i <br />Tank Buoyancy, Rotten Robbie No 69, <br />Manteca CA, dwg 17366-001, 10ft DWT <br />Date Printed: 9/7/2023 Page 39 of 46
