Among the different types of aircraft structures, the shell structures efficiently transmit the: 1.normal bending stresses 2.tangent bending stresses 3.torsional moment 4.shear stresses The combination regrouping all the correct statements is:

1) Which components do a semi-monocoque fuselage consists of?

2) 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:

4) The fuselage of an aircraft consists, among others, of stringers whose purpose is to:

5) Some aeroplanes have a "waist" or "coke bottle" contoured fuselage. This is done to:
