A rigid truck with no headboard carries 10 tonnes of rigid packets, each at least 0.5 tonne, secured by two tie downs. What minimum combined rated strength is needed?
ʻOku uta ha loli sino maʻu ʻoku ʻikai ha papa taʻofi ʻi muʻa ʻi he tone ʻe 10 ʻo e ngaahi kofukofu fefeka ʻoku taki tone ʻe 0.5 pe mamafa ange, kuo fakamaʻu ʻaki ʻa e haʻi ʻe 2. Ko e hā e mālohinga fakakātoa siʻisiʻi taha kuo fakafuofua ki he ngaahi haʻí ʻoku fiemaʻú?
Without a headboard, the rigid packets described need lashings with combined rated strength of at least twice the load's weight: 20 tonnes for a 10-tonne load.

This calculation applies to packets weighing at least 0.5 tonne each. Correct lashing methods, suitable anchor points and the performance of the complete restraint system remain essential.
