I am writing a report on damage to a screw used for a machine.<br/><br/>"The surface of the screw was remarkably oxidized by heat.<br/>Furthermore, thread damage is possible."<br/><br/>My question is whether i should write the second sentence in the past tense "Furtherefore, thread damage was possible."<br/><br/>I would have thought that it is okay to write it in the present tense because it means "the existence of thread damage is possible presently."<br/><br/>What do you think?
