The figure given below is the section
of the reinforced concrete short column.
Calculate the stress in the concrete
and the stress in the steel,if the
axial load of 780KN is applied to
the column.
Young′s modulus of steel=210KN/mm^2
Young′s modulus of concrete=14KN/mm^2
diameter of the steel bars=20mm
how many ways can you
exchange 1 dollar using
(1,5,10,25,50) cents
example
1 dollar(100 cents)=2×50cents
=1×50+2×25=4×25
=1×50+1×25+1×10+1×5+10×1
and so on
how many all the ways ?
