3. A beam is loaded as shown. El is constant. The
vertical reactions at B and C are equal to 80kN. For
items a, b and c, use the coordinate system shown,
with x=0 at point A.
a. Derive the moment function, M(x), in
terms of El, using Macaulay Functions.
b. Derive the slope function, 0(x) in terms
of El.
c. Derive the deflection function, y(x) in
terms of El.
The modulus of elasticity is 200 GPa.
d. Determine the required moment of inertia,
I, if
i. The absolute value of the
maximum deflection should not
exceed 6mm; and
ii. The absolute value of the slope
should not exceed 0.01 radians at
А.
