Part of the landing gear for a light plane is shown. Determine the compressive stress in the strut AB caused by a landing reaction R = 30 kN. Strut AB is inclined at 30 degrees %3D with the vertical. Neglect the weights of the members. Hollow strut OD 40 mm ID-30 mm 200 mm-+ 450 mm

Calculate the forces in members BE and BD of the loaded truss. The forces are positive if in tension, negative if in compression. Assume F = 7.5 kN, a = 2.5m, b = 3 m, c = 2 m, and d = 2 m. A F Answers: BE= BD = a i i B b E a b O KN KN

A rigid ban AB and "CD" as shown are supported by pins at "A" & "C" and two ross. Determine the maximum force 'p' that can be applied as given if it's vertical movement is limited to 5 mm. Neglect the weight of all the members. www A 3m 3m Aluminium P L = 2m, A= 500m² E =70 GPA 3m IB 3m Steel L=2m A= 300m² E = 2006/ D
