(2) (b) A simply supported reinforced concrete beam la constructed of
20 Mpa and Pe415 steel. It supports factored dead load' of 5
IcN/m and tinctored Live' load of 35 IN/m. Bending Moment
diagram, shear foce diagram and the cross section at maximum
bending moment are shown in Fig. 2(b). If two 20rhm diameter
bars are to be curtailed, find the actual point of curtoilment,
check developmert length and shcor capacity at point of cut off.
