I am not sure which formula to apply, can anyone help me out?
28. A square copper bar experiences only elastic
deformation if it is stressed less than 95MPa.
To support a load of 1340kg without exceeding this stress,
the minimum square cross-section ( i.e. width of one side
of the square cross section) required is
a) 1.8mm square
b) 3.6 mm square
c) 23.6mm square
d) 11.8mm square
