Assuming you have been offered a job position as the lead Engineer to supervise the restoration of a steel bridge that collapsed due to fracture. The laboratory results of the wreckage (a truss) given to you show an internal crack whose length is 0.026 mm and radius of curvature is 0.00028mm. If the material theoretical fracture strength is 2000 MPa, determine the allowable applied stress.
