Question
A simply supported beam AB=9 m has a hollow rectangular cross-
section with 17 cm as width, 27 cm as depth and thickness as 2 cm is
subjected to a point load of 6 N & 7 N acting at Cand D respectively
and a uniformly distributed load (UDL) of 6 N/m starts from mid-
span and ends at the right support of the beam. Determine the
maximum bending stress and the bending stress at 2 cm from the top.
Take AC=1 m & CD=2 m.
i) Reaction force at B=
ii) Reaction Force at A=
iii) The distance from B at which the shear Force value changes from
to "+" =
iv) Maximum Bending Moment (Please write the Maximum bending
moment valve in "Nm")=
v) Moment of Inertia, I=
vi) Maximum bending stress =
vii) Bending stress at 2 cm from the top%D
