For FAIL-SAFE designed structural parts: 1.The mounting principle is parallel mounting. 2.No routine check is necessary. 3.L33The member is removed at the end of the calculated life cycle. 4.Certain components may not be accessible. 5.The principle is the redundancy of components 6.The failure of a member causes the loads to be shared between the other system components. The combination regrouping all the correct statements is:
