Example Hook Calculation

The hook is lifting a load of 25000N.

 The stress values plotting against r are shown below:



 

The tensile stress at the inner surface is calculated at 126.76 N/mm2 and the compressive stress at the outer surface is calculated at -42,25 N/mm2...

This section profile results in a tensile stress three times greater than the compressive stress.  A more efficient section with the stresses balanced would result from having a wider inner section and a thinner outer section.
