The structure in the figure is composed of two rigid bars (AB and CD) and two vertical rods made of aluminum and steel. All connections are pin joints. Determine the maximum force P that can be applied to the structure if the vertical displacement of its point of application is limited to 4 mm. Neglect the weights of the members. Answer must be in kN. For Aluminum: A = 454 mm? and E = 69 GPa, for steel: A= 358 mm2 and E 206 GPa. Alumimum 3m 4m 4m
