A Ni-Mo-V alloy plate with the yield strength of 84,500.0psi, fracture toughness of 33,800.0psiin, and the crack growth behavior shown in the graph is t=0.375 in thick and b=12.5 in wide. The plate is to be loaded with a released tensile load fluctuating from 4,687.5lb to 75,000.0lb, applied in the longitudinal direction. A through-the-thickness crack of length 0.125 in has been detected at one edge. How many more cycles of the released tensile loading would you predict could be applied before catastrophic fracture occurs
