A = Area
x = Distance from neutral axis to farthest fibre
I = Moment of Inertia
S = Section Modulus
r = Radius of gyration
The strut width has been deliberatelty increased to show the geometry.
Rectangle struts are the simplest of all strut types, and consequently the fastest to compute. This strut may be used with ring, star, and flange hub types, without the need for cutting mitred ends.
To account for hubs, you can specify the hub radius in the ‘Strut Options’ where you can also specify the strut ingress distance – i.e., what portion of the strut is clamped, fixed or inserted within the hub.
