What should the bearing strength of the sheet metal and the shear strength of the rivet be? o :## relatively equal True or False: the shear strength of the rivet must be greater than the bearing strength of the sheet metal o :## True What are the parts of an aircraft structure designed to carry loads and or stresses called? o :## structural members What is a spar? o :## The wings principle structural member What are the Ailerons, Rudder, and Elevator? o :## The three Primary flight Control Surfaces of an aircraft What are the three secondary control surfaces? 2024/2025 2 | P a g e o :## The Slats, Spoilers, and Flaps. What are the purposes of Slats and Flaps? o :## To increase the camber of a wing, and increase lift at slower speeds What is the purpose of spoilers? o :## To slow the aircraft and disrupt the lift of an airfoil. What are structural supports that are under the aircraft skin? o :## Longerons, bulkheads, and stringers True or False: Longerons do not run the entire length of the aircraft fuselage. o :## False.
