In a combined footing if shear stress exceeds 5 kg/cm2, the nominal stirrups provided are: A. 6 legged B. 8 legged C. 10 legged D. 12 legged

The correct answer is A. 6 legged.

The nominal stirrups provided in a combined footing if shear stress exceeds 5 kg/cm2 are 6 legged. This is because the shear stress in a combined footing is usually high, and 6 legged stirrups are able to provide the necessary shear strength.

Stirrups are a type of reinforcement that is used in concrete to resist shear forces. They are usually made of steel and are placed perpendicular to the main reinforcement. The number of legs in a stirrup refers to the number of bars that are bent around the main reinforcement.

The size and spacing of stirrups are determined by the shear stress in the concrete. The higher the shear stress,
