Two columns 50 cm × 50 cm and 60 cm × 60 cm carry 80 tonnes and 120 tonnes of loads respectively. The centre to centre distance between columns is 5.00 metres. The permissible bearing capacity of the soil is 20 t/m2. If the footing is not to project more than 25 cm beyond the outside of the smaller column, pick up the correct design parameters of the footing from the following:
Distance of C.G. of the loads from the smaller column = 3.00 m
The length of the foundation slab = 7.00 m
Area of footing slab = 11.00 m2
All the above
