English to Hebrew Tech/Engineering General / Conversation / Greetings / Letters

In the following sense:

"The calculations shall be made with the platform in the most unfavorable position with the maximum allowable inclination of the chassis defined by the manufacturer."

I.e., some positions are unfavorable because they may cause the entire vehicle to overturn.
We consider the _most_ unfavorable one, i.e., the one at which the vehicle is most easy to overturn.

I just can't figure out how to say this in Hebrew.
