Q1: If W is the load on a circular slab of radius R, the maximum circumferential moment at the centre of the slab, is

ANS:C -

The maximum circumferential moment at the center of a circular slab subjected to a uniformly distributed load W can be calculated using basic principles of structural mechanics. This moment occurs at the center of the circular slab and represents the maximum bending moment induced by the applied load. The formula to calculate the maximum circumferential moment (maxMmax​) at the center of a circular slab subjected to a uniformly distributed load is given by: Mmax​=2W⋅R​ Where:

• W = Uniformly distributed load on the circular slab
• R = Radius of the circular slab

This formula is derived from the fact that the maximum bending moment occurs at the center of the circular slab when subjected to a uniformly distributed load. At this location, the moment arm is equal to the radius R, and the maximum moment is reached when the load is uniformly distributed over the entire slab. Therefore, to find the maximum circumferential moment at the center of the circular slab, simply multiply the load W by the radius R and divide the result by 2. Mmax​=2W⋅R​ This equation provides the maximum circumferential moment at the center of the circular slab, which is essential for analyzing and designing the slab's structural capacity and reinforcement requirements.
