Figure Q5(a) shows a plane truss supported by a horizontal spring at the top node. The truss members are of a solid circular cross section having a diameter of 20 mm and an elastic modulus (E) of 80 GPa (10° N/m2). The spring has a stiffness constant of k-2000 kN/m. A point load of 15 kN is applied at the top node. The direction of the load is indicated in the figure. The code numbers for elements, nodes, DOFS, and...

The below truss is made from three bars of the same steel material, all of which have circular cross sections with different diameters. The Young modulus of steel is E= 200 GPa, and yield stress of steel is Gyöeld=200 MPa (in both tension and compression). The force P=7 kN is applied at point C as shown (see Figure 4). All bars are pin connected at their ends. (a) Determine the minimum diameter of the bars so that buckling will not...

Determine the horizontal displacement at the node where 20 kN is applied. Also compute the reaction forces at the supports. The stiffness method (see Week 9) can be used. Note that the degrees of freedom (DOFs) of the truss are indicated in the figure. Take EA as constant. 12. Determine the horizontal displacement at the node where 20 kN is applied. Also compute the reaction forces at the supports. The stiffness method (see Week 9) can be used. Note that...
