SUMMARY

The discussion focuses on calculating the maximum load that can be applied to an offset link connected to two cables, given its dimensions and allowable normal stress. The offset link has a width of 200mm and a thickness of 35mm, with an allowable normal stress of 74 MPa. The primary equation for determining stress, Stress = F/A, is highlighted as essential for this calculation. Additionally, the need to consider bending stresses due to internal bending moments from eccentric loading is emphasized, indicating a comprehensive approach to solving the problem.

How is the following question done?


Homework Statement


An offset link is connected to 2 cables like shown in the image attached.

The offset link has a width 'w', of 200mm (or 0.2m) and a thickness of 35mm (or 0.035m). It has an allowable normal stress of 74 MPa.

What is the maximum load that can be applied to the cables?


Homework Equations



Based on the values given, I'm assuming that the stress would need to be found.
So... Stress = F/A is relevant.

Not sure what other equations can be used

The Attempt at a Solution



I have no idea how to approach this question. A friend gave me a hint and said to first find the critical location of failing (no idea how to do that either!).

In addition to the P/A axial stress, you also have bending stresses due to internal bending moments from the eccentric loading maximum about the centroidal axis of the link. What is that moment?
