A cantilever beam of rectangular cross – section is 1 m deep and 0.6 m thick. If the beam were to be 0.6 m deep and 1 m thick then the beam would
(a) Be weakened 0.5 times
(b) Be weakened 0.6 times
(c) Be strengthened 0.6 times
(d) Have the same strength as the original beam because the cross – sectional area remains the same
