With that in mind, Sik put a roof over his herd's heads. He installed the first Hoop Beef System in the region, enclosing 207 cattle with the deeply bedded, totally roofed structure.

Area = 2.t.dx. Combining these, we can calculate the longitudinal stress: σh = P.2r.dx / 2.t.dx. σh = Pr / t. Result. Comparing the two results, we can see that the hoop stress in the casing is ...
