A drawing of a scale model aircraft flying at constant velocity in level flight is shown.
 

Assume that the lift acts as a point load only on each wing and is located as shown in the drawing.

  1. In the box below, draw the free body diagram of the forces acting on the aircraft.   (1 mark)

 

  1. Draw both a shear force diagram and a bending moment diagram of the aircraft as the forces act across the wingspan of the aircraft.   (5 marks)

A drawing of an aircraft in flight is shown. This aircraft maintains a constant velocity when in level flight.
 

On the following page, draw a labelled shear force diagram AND a labelled bending moment diagram for this situation. Include a labelled free body diagram to support your answer.

Assume the centre of lift on each wing acts as a point load located 7.5 m from the centre line of the plane.

Calculations can be completed in the space below.   (6 marks)
