A cantilever beam of rectangular cross section is subjected to a load W at its free end. If the depth of the beam is doubled and the load is halved, the deflection of the free end as compared to original deflection will be _______.
Show Hint
Bending deflection is highly sensitive to the depth of the beam because depth is cubed in the denominator of the stiffness term.
Doubling depth alone reduces deflection to $1/8$, and halving the load further reduces it to $1/16$.
