The space truss above is supported by ball-and-socket joint at points A, B, and E. A single force F = {-200i +300j +50k} N is applied at point D. Take the following: • UDA = {-0.267i -0.802j -0.535k} • UDB = {+0.923i +0.231j -0.308k} • UDc = {-0.371i +0.557j -0.743k} Which of the following is closest to the force in member DB?

The metallic hollow pipe shown in Figure Q1 is fixed at both its ends, and is under axial compression. The pipe has an external diameter D = 74 mm, an internal diameter d = 49 mm, and a length L = 5.06 m. The Young's Modulus of the metal used to manufacture the pipe is: E = 157.59 GPa. Figure Q1 Calculate the critical buckling load Pcrit using Euler's Formula. Assume the critical buckling load obtained through your calculations is valid in this case, and does not require verification. Use π = 3.14159 if needed. Express your answer in the unit: Newton (N).

The link shown in the figure is 45 mm wide and is cut from a low-carbon steel bar stock having a minimum yield strength of 165 MPa. A force of P= 900 N is applied at point C. The end-condition constants are C= 1 and C= 1.2 for buckling in and out of the plane of the drawing, respectively. Using a design factor nd= 4.5, find a suitable thickness for the link. -900 mm A 500 mm 750 mm P
