You are supplying pressurised water through a copper tube (oy = 180 MPa, K1c = 18 MPa m72). The tube is subjected to a fluctuating load of 100 MPa which is opening a surface crack with an initial length of 3.5 mm ? How many cycles will cause this tube to fail in fatigue? Assume Y=1 & A = 7 x 10-13 m(MN - m3/2)-3. The number of cycles to fatigue failure is governed by the follow equation (as provided in contact session):

Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…
