Question 1 (Boundary Value Problem – without differentiation)
a) A system is represented by a differential equation y"- xy' +3y = 62x with the
boundary conditions y (1) = 1 and y (2) =10. Find the response y from 1 to 2 with an
increment h =0,2
b) The radial displacement pressure vessel across the thickness (inner radius a=125mm,
outer radius b=200mm) follows a differential equation.

In a condition of internal pressure, the displacement of inside (r= a) outside (r = b) should be
sct as 0.0968275mm and 0.0769240 mm respectively.
Illustrate the cross-section of the pressure vessel and the boundary condition of the
displacement. Ncxt, illustrate the 1-dimensional model of across the thickness if divided by
four nodes with the same distance (four equidistance nodes). Determine the radial
displacement profile using the Finite Difference Method.
