Mechanical Property
The metal supports are designed to withstand the nominal force F and the pressure of the wind V applied
at 0.25m from the top. Under these loads, the safety factor with respect to the elastic limit of the steel is la
rger than 1.8. The post also resists a torque equal to (F+V) ×1m. Tests shows the load intervened when
breaking is around 2 times of design load.
