Determine the relative displacement of point D from O for the elastic steel bar of variable...
Question 1 (25%) For the truss shown on figure 1, determine the horizontal displacement of point C when P 1000 N and P2 -0. Also, determine the vertical displacement of point F when P 0 et P2 1000 N. All members are prismatic and have the same elastic modulus fixed at 200 GPa. Area of each member is indicated in brackets (mm2). A (4000)B(400C (3000 (3000 2,75 D(5000 E(5000) Pi Figure 1
A 3 m rigid bar AB is supported with a vertical translational spring at A and a pin at B The bar is subjected to a linearly varying distributed load with maximum intensity g Calculate the vertical deformation of the spring if the spring constant is 700 kN/m. (ans: 21.43 mm) 2. A steel cable with a nominal diameter of 25 mm is used in a construction yard to lift a bridge section weighing 38 kN. The cable has an...
