For the cantilever plane truss in the figure above, use MATLAB to determine: 1)Nodal displacements 2)Reaction Forces 3)Element Strains and Stresses Assuming that both supports are going to be fixed and the values of E = 70 GPa and A = 0.003125

A uniform stone slab weighs 400 lb and is suspended by 3 cables and subjected to a downward vertical load as shown in the figure and parameter table. A B F parameter L1 L2 L3 value units 2 ft 4 ft 3 ft F 150 lb The tension in cable A is 200 * lb The tension in cable Bis 35.7 X lb The tension in cable C'is 314 X lb

Analyse the statically determinate bar illustrated below by expressing the loading as a single function using Macaulay brackets and the Dirac delta, integrating to find th axial force and integrating again to find the displacements, applying the boundary conditions appropriately. Find the axial force in the bar at point A and the displaceme at point B. The cross section of the bar is constant with EA = 18000 kN. a = 4 m, b = 2 m, c = 2 m and d = 4 m. w1 = 12 kN/m, w2 = 17 kN/m,, P1 = 12 kN and P2 = 19kN. a W1 L/2 W2 Multiple Choice Answers Multiple Choice Answer: Axial force at point A (kN, tension positive): a. 3.31 b. 31.97 c. 37.33 d. 31 Multiple Choice Answer: Displacement at point B (mm, positive to right): a. 0.0061 b. 0.0395 c. 0.0193 d. 0.0261 Axial force at point A (kN, tension positive): Displacement at point B (mm, positive to right): L/2 P1 P2 (type in your multiple choice answer, e.g. a, b, c or d) (type in your multiple choice answer, e.g. a, b, c or d)
