When a uniform beam is simply supported at its ends the deflection at the centre
span is given by
Y=5wl^4/384EI
Where
w is the distributed load per unit length
I is the length between supports
E is Youngs Modulus
I is the 2nd moments of cross sectional area.
Find the percentage change in y when I decreases by 5%
