Deflection of an I-Beam(100 %)
You are to develop a program that calculates the vertical deflection of a beam
subjected to a force acting on it as given in Figure 1. The I-Beam has length,
L = 2m with its left end fixed at the wall (no deflection at wall). The right end of
the beam is applied with a vertical load force P with a vertical deflection function
Px?

The beam has a cross-sectional diagram in Figure 2 and has the following
properties.
• w = 150mm for 0 <x < L/2; w = 90mm for L/2 < x < L
• h = 100mm; b= 5mm; t = 8mm
Assume that the Young's Modulus (the inherent 'strength' of the beam) E =
7 x 1010Pa and that the load at the tip P = 3kN. Your code should have the
following:
1. A function or subroutine to compute the second moment of inertia I(x)
2. A function or subroutine to compute the overall deflection v(x) of the I-
beam.
