Calculate the spacing between contraction joints by using the following data:
Width of slab = 4.52 m
The thickness of the slab = 25 cm
Coefficient of friction = 1.5
Allowable tensile stress in steel = 1400 kg/cm2
Diameter of bar = 12 mm
Spacing between the bar = 300 mm
Take \(\gamma_c\) = 2400 kg/m3
