The following two step bar is subjected to an axial load P. The cross-section of the bar is rectangle with a thickness of t=4.9mm, and the Young's modulus is E=88 GPa. Using two elements with equal lengths, find the stiffness matrix of both elements. Suppose that the stiffness matrices are in the form of а K₁= [Ca -a what is the value of a + b? (Hint: The stiffness matrix of each element should be obtained in N/m) 0.1 m aN/m, K₂= 0.5 m b [b b 2 0.0 0.5 m
