Rotation of axes
The centroid, or center of gravity, of any object is the point within that object from which the force of gravity appears to act. • An object will remain at rest if it is balanced on any point along a vertical line passing through its center of gravity.
Moment of Inertia - It is a measure of an object’s resistance to changes to its rotation. Also defined as the capacity of a cross-section to resist bending. . It must be specified with respect to a chosen axis of rotation. • It is usually quantified in m4 or kgm2.

Shear force - It is that force which is trying to shear off a beam at a particular section.
Bending moment- It is a reaction offered when a beam (element) is subjected to a force at a distance or a moment causing bending.

open channel flow hand written notes
Open Channel flow
Open Chanel flow is that type of flow which is neither completely enclosed by the boundaries nor is under any external pressure but gravity. It is subjected to atmospheric pressure. e.g. Rivers, natural and artificial canals, streams, channels etc. Partially filled pipes flow is also an example of open channel flow.

Truss handwritten notes
There are four main assumptions made in the
analysis of truss
1 Truss members are connected together at their ends only.
2 Truss are connected together by frictionless pins.
3 The truss structure is loaded only at the joints.
4 The weights of the members may be neglected.

levelling
The art of determining the relative heights of points on the surface of the earth is termed as “levelling.”
Levelling surface is a surface that is perpendicular to the direction of gravity at every point .EX :-Surface of still water in a lack ,surface of a sea which is not affected by tides geoid.

tacheometric surveying
Tacheometer is a theodolite arranged with a stadia diaphram having three horizontal lines. The two stadia lines i.e. ,upper and lower are equidistant from the central horizontal line.
1. Tacheometric surveying is also known as the optical distance measuring method because an optical instrument i.e. a tacheo-meter is used in the surveying .
2. Various patterns of stadia diaphram are upper stadia diaphragam and lower stadia diaphragam.

Introduction of Fluid mechanics
Fluid -Liquid and gases both are having the property of continuous deformation under the the action of shear or tangential force .This property of continuously deformation is also known as flow property and Hence Liquid and gases are kept in different category which is far away from the solids and this category is known as fluid.

Types of foundation
 |
Every building consists of two basic components
1) the super-structure
2) the substructure or foundations.
The super-structure is usually the part of the building which is above ground.The substructure or
foundations is the lower portion of the building, usually located below ground level.
It transmits the load of the super-structure to the sub-soil.

ROOF
A roof may be defined as the uppermost part of the building, provided
as a structural covering, to
protect the building from weather (i.e. from rain, sun, wind, etc.).
Some important features of roofs:
protect the building from weather (i.e. from rain, sun, wind, etc.).
Some important features of roofs:
Structurally,
a roof is constructed in the same way as an upper floor, though the shape of
its
upper surface may be different.
Basically, a roof consists of structural elements which support roof coverings.
structural element may be trusses, portals, beams, slabs (with or without beams), shells or
domes.

INTRODUCTION
nA stair is
a set of steps leading from one floor to
the other. It is provided to afford
the means of
ascent and descent between
various floors of a
building.
nThe room or
enclosure of the building, in which
the stair is located is known as stair-case.
n The opening
or space occupied by the stair is
known as a stairway. It should be suitably located
in a building.
nIn a
domestic building the stairs should be
centrally located to provide easy access
to all the
rooms.
nIn public
buildings, stairs should be located near
the entrance. In big buildings, there
can be more
than one stair.
Stairs may be constructed of timber, bricks, stone,
steel or reinforced
cement concrete.
