Problem of finite element analysis(urgent)
Consider the truss system shown in Fig. 2 modelled by three elements. The element numbers are shown in brackets. The node numbers are as indicated in the figure. Suppose that all the trusses have a cross sectional area of A = 0.1 m2 and Young’s modulus E = 70 GPa. Determine the displacements at all the nodes if the force P = 2000 N. The length L = 2 m.

Hoops stress
A steel ring of outer diameter 300mm and internal diameter of 200mm is shrunked unto a solid steel shaft , the interference is arranged such that the radial pressure between the meeting surfaces will not fall bellow 300MN/m^2 while the assembly rotates in circles. If the maximum circumferencial stress on the inside of d surface of the ring is limited to 240MN/m^2. Determine the maximum speed at which the assembly can be rotated . Assuming that no relative slip occur between the shaft and the ring.
