2. For the pin-jointed truss shown in Figure Q2.1 applied at node 4. The Young's modulus E(GPa) is the same for the three truss vertical downward force P(kN) is a members. The cross sectional area of each of the truss members is indicated below and expressed in terms of a constant A. By using the stiffness method: (a) Compute the reduced stiffness matrix Kg [5 marks [10 marks (b) Calculate the global displacements of node 4 in terms of P,...
Q1 The pin-jointed wood truss shown in Figure Q1a is subjected to a point load P 24 kN at joint B a) Show that the truss is statically determinant. Indicate zero force members. Determine the force in members BC, CF, GF of the truss [10 marks] b) The truss is made of wooden joists (Young modulus E 10 GPa) with a rectangular cross-section having dimensions of 47mm × 150mm. The vertical displacement of joint B is measured to be 10...
AB length is 4000mm AD length is 3000mm A pin jointed frame ABCD is supported by a pinned support at A, a roller at B and is subjected to the loading indicated in Figure Q1. All members have circular cross-section and all are made of steel materials with same cross-section. Determine the support reactions at A and B Determine all the member forces Find out the horizontal displacement at point C using a table template as shown in Table Q1....
