QUESTION 6
A simply supported beam with a constant cross section is subjected to a static load P as
shown in Figure Q6. The beam experiences a deflection of \delta _(s)=(PL^(3))/(48EI) at mid span. Given
that the beam length, L=5m, the Modulus of Elasticity, E=230GPa, the moment of inertia,
I=5\times 10^(6)mm^(4) and P=300kg. Find the equivalent spring constant of the beam, frequency
and maximum speed of the vibration if maximum amplitute of vibration is 20 mm .
