Answer Posted / asad ali
let suppose you have given cube size is (6*6*6 inch)or(15*15*15 cm) OK
we know we that 1N = 1kg.m/sec.sq.....(1)
first we convert KN to N OK
25KN = 25000N
according to physical equation F=ma or W=Mg......(2)
m=mass , g= gravitational force = 9.81m/sec.sq OK
so according to eq (1)
25000N=25000kg.m/sec.sq
there fore divide the (g) \
25000kg.m/sec.sq
---------------------- = 2548.41kg OK
9.81m/sec.s
and the given area of cube = 15*15 = 225cm.sq
stress in conc: cube = 2548.41kg
-----------
225cm.sq
stress = 11.326Kg/cm^2
OK
