Question 16-25
Among different types of aircraft structures shell structures efficiently transmit 1 normal bending stresses2 tangent bending stresses3 torsional moment4 shear stressesthe combination regrouping all correct statements Compression then tension. Shell structure another name monocoque construction the monocoque design uses stressed skin to support almost all imposed loads this structure can be very strong but cannot tolerate dents or deformation of surface this characteristic easily demonstrated a thin aluminum beverage can you can exert considerable force to ends of can without causing any damage however if side of can dented only slightly can will collapse easily the true monocoque construction mainly consists of skin formers bulkheads the formers bulkheads provide shape the fuselage since no bracing members are present skin must be strong enough to keep fuselage rigid thus a significant problem involved in monocoque construction maintaining enough strength while keeping weight within allowable limits due to limitations of monocoque design a semi monocoque structure used on many of today's aircraft. Question 16-26
On a non stressed skin type wing wing structure elements which take up vertical bending moments mx are Compression then tension. In a fixed wing aircraft spar often main structural member of wing multiple spars on a commercial aeroplane spar+stringers on a light aircraft the spars are able to carry upward (resulting from wing lift force that supports fuselage in flight) downward (whilst stationary on ground due to weight of structure fuel carried in wings wing mounted engines if used) bending moments.
