Question

Calculate the axial force and displacement.

Analyse the statically indeterminate bar illustrated below by integrating the governing differential equation to find the axial force and displacements, applying the boundary conditions appropriately. Find the axial force and the displacement at point A. The cross section of the bar is constant with EA = 8000 kN. a = 3.0 m, b = 2.5 m, c = 3.0 m and d = 0.5 m. w = 6 kN/m, and P = 9 kN. The bar is also subjected to a temperature increase at the time the load is applied. This temperature change varies linearly along the length of the bar and is Tl = 30 degree C at the left hand end of the bar and T2 = 45 degree C at the right hand end (the coefficient of thermal expansion at = 1.0e-05 degree C-1). The support indicated undergoes a prescribed displacement of u = 3 mm. Axial force at point A(kN, tension positive): Displacement at point A( mm, positive to right):
