Suppose that you used 70 quadratic elements to discretise a bar system (mesh). What is the size of the assembled stiffness matrix? (Hint: if the size of the matrix is 10 by 10, then write 10 in the answer box).

A load P is supported by a structure consisting of rigid bar ABC, two identical solid aluminum alloy [E-73 GPa] rods (1), and a solid bronze [E = 105 GPa] rod (2). The aluminum rods (1) each have a diameter of 12 mm and a length of L₁ - 2.5 m. They are symmetrically positioned relative to middle rod (2) and the applied load P. Bronze rod (2) has a diameter of 22 mm and a length of L₂ - 1.7 m. If all bars are unstressed before the load P is applied, determine the normal stresses in the aluminum and bronze rods after a load of P - 80 KN is applied to the rigid bar. L₁ Answer: 0₁- i 0₂- 164 L2 (1) (1) MPa MPa
