The report describes a temporary instrumentation system installed on the STR. CHARLES M. BEEGHLY to measure longitudinal vertical hull bending stresses during the first voyage after lengthening to 806 feet overall. A calibration was performed the night before departure which verified that the measurements correspond closely with calculated values. Data were taken during the first loading at Taconite Harbor which show that bending stresses are well within the limits established by the loading manual. During the only period of bad weather encountered on the first voyage, springing stresses having a maximum peak-to-trough excursion of approximately 4,000 psi were measured. (Author)
