Mark Summary + _ Marks allocated Exemplary responses should: Task 1 Correctly describes the names, directions, and points/lines of application of the four forces. Answers are general and not specific to cruise conditions. b) 5 Show free body and extended free body diagrams with all four forces, and their points/lines of application, clearly labelled. Show relative wind. Establish coordinate system/sign convention for force/torque components. Establish algebraic symbols for each force and point/line of application. c) 6 Derive algebraic expressions that place constraints on the forces and torques acting in mechanical equilibrium. Explain the physical meanings of each term in the expressions. Correctly calculate the total mass of plane and passengers. Calculate weight based on the total mass. - . o Scenario: During the lectures, we learned that there are four main forces acting on a fixed-wing aircraft while it is flying; o thelift (FL), e the gravitational force or weight (Fg), e the thrust (Fy), and e thedrag (Fp). Each of these forces may change direction, magnitude, and/or point of application during different stages of flight. In this assignment, you will qualitatively and quantitatively examine some consequences of these changes. Complete each of the two Tasks requested below. Provide your working and conclusions in this template. You may use information from your lectures or any other external sources (appropriately referenced). Anything that is highlighted is a prompt for you please remove the prompt once your response is completed. Other: Please observe the following: All non-original! photographs, diagrams and sources must be referenced appropriately in the bibliography section below (you do not need to reference your own original diagrams). Use the AGPS Task 1: Equilibrium conditions Consider a typical tractor-configuration aircraft (one where the engine is ahead of the wing, e.g. Cessna Skyhawk). Construct responses to the following prompts and questions using the information from your lectures or any other external sources (appropriately referenced): 1a: Describe the airborne forces as vectors acting on the aircraft. Where on the aircraft (with respect to its centre of mass) do each of these forces act? What are the names for those positions? > 1b: Draw your own free body diagram, and your own extended free body diagram showing where each of the four forces act relative to the centre of mass during cruise (i.e., level flight with constant velocity). On your extended free body diagram, indicate the direction of the relative wind, assuming that the surrounding air is initially stationary. Free Body diagram Fo Fs > Extended Free Body diagram > 1c: Using your extended free body diagram, establish the translational and rotational equilibrium conditions during cruise. Your response should explain how you arrived at your final expressions and interpret their physical significance
