Question: problem 32 the threebar truss abc shown in figure part...

Question details

Problem 3-2 The three-bar truss ABC shown in figure part a has a span L-3 m and is constructed of steel pipes having cross-sectional area A -4000 mm2 and modulus of elasticity E-200 GPa. Identical loads P act both vertically and hori- zontally at joint C, as shown. (a) If P-400 kN, what is the horizontal displacement of joint B? (b) What is the maximum permissible load value Pmax if the displacement of joint B is limited to 1.5 mm? P-400 kN P-400 kN 450 45°
