### What branch of mechanics deals with equilibrium?

The branch of mechanics that deals with equilibrium is known as statics. It focuses on studying the condition where there are no net forces acting on a body, and when a system of forces acts on a body, which may lie on a single or different planes.

In civil engineering, there are various methods used for estimating quantities of materials and items. These include the centreline method, crossing method for masonry walls, out-to-out and in-to-in method, bay method, and service unit method.

### What are the methods of estimation in civil engineering works?

In civil engineering works, different methods are used for estimating quantities of materials such as bricks, tiles, sand, stone, ballast, and cement. Bricks and tiles are counted according to size, quality, and class, while sand, stone, ballast, etc. are measured in cubic meters or cubic feet. Cement is measured by weight in a 50 kg bag. Moreover, there are various methods of taking out estimates for different types of buildings.

### What are the methods of cost comparison?

The methods of cost comparison include market survey method, index number method, ratio method, cost-capacity factor method, historical cost method and more. These methods involve comparing the costs of similar products, services or assets to determine the most cost-effective option.

### What is estimate civil engineering book value?

The estimate civil engineering book value refers to the amount stated in the account book after required depreciation is considered. This value represents the original cost subtracted by the accumulated depreciation up to the previous year for a specific property.

### How does a structural engineer perform an accurate analysis?

A structural engineer performs an accurate analysis by determining information such as loads, geometry, support conditions and material properties. Results typically include reactions, stresses and displacements which are compared to failure criteria.
