SAE J/ISO 3471 supersedes SAE J1040 for ROPS (RollOver Protective Structures).
In 3471 Table 1 – Force and energy equations it specifies energy, U, in units of joules. However, in the column for Lateral load energy, it calls out factors of m (machine mass). Mass in units of kg is not energy. Any ideas?
I would attach the 3471 document but it is copyrighted.
