Q. 2. Identify different methods of supports for structures:
Supports: a member of the structure that helps to resists load like the other member. The
supports have different types, applications and reactions that define below. It used to define the
forces in different terms like how the forces transferred to the ground. Here defines different
example of the supports with their example, limitations and reaction.
Fixed Support:
The most inflexible part of the support or the connection that includes all the members in
rotations and translation as it can rotate or move in any direction. The column or the pole of the
concrete is the example of the fixed support. The application of the fixed support is like, it is
beneficial in the use of single support. The advantage of fixed support is the downfall as some
of the structure need little deflection to protect the surrounding material. Gain the strength with
the concrete and its durability is a reduction when the design is supported. The representation is
as below:
Figure 1: Fixed Support
Pinned Support:
It is a common type of support that compare to civil engineering like the hinge. Hinge is the
pinned support that allows occurring the rotation, not the translation. For example, if an elbow
can extend and it can’t be a move to the forearm. In the application area, it used in the trusses by
link with the multiple members that used to join by the connections. In the benefit of this pinned
support is that the member includes only the moment of internal forces. The limitation of the
pinned forces is that a structure cannot be completely restrained without the need for two
different (Carigliano, 2016).

Figure 2: Pin Support
Roller support:
This type of support resists with the vertical, not with the horizontal support. The roller support
is free to move in any direction of horizontal. The bridge is the application of the roller support
as it contains roller support at the one end for the account of vertical displacement and changes
in the temperature with the expansion. The limitation of the roller support is as it does not
support the horizontal forces (Anupoju, 2016).

Simple support:
This support is based on the resting place of the members in the form of external structure. This
support is the same as the roller support in terms of restraining the vertical forces not the
structural. The force transfer to the external forces as the members rests on the external
structure. The application of then simple support is used in different structure and confirm and
this process can’t be translating to other support (mit, 2019).

Q. 3. Produce valid factors for live loads, dead loads and imposed loads
The factor of safety:
The factors of safety are related to the carrying load of the capacity of a system beyond the
capacity of the system support. This process used in the construction of bridges, buildings,
safety equipment and fall protection. this process used to define the requirements of the
stronger system for the construction. Determine the factor of safety with the strength tests and
how much the weight can be managed by the system. the safety factor determines by the ductile
material with use the yield strength. On the other side, the ultimate strength uses by the brittle
material (Wilhite, 2018).
Safety for live load:
This load is also known as imposed load and this is usually dynamic, temporary and
changeable. This kind of load used in vehicle traffic, furniture, occupants and in the other
equipment’s. this load includes the intensity that depends on the time of the day. Understanding
with an example, an office building increases the live load at the weekday compare to the less
load at weekends or night. The live load involves or include in the impact with the vibration or
the acceleration is related to the distributed and concentrated.
Safety for dead load:
These loads are the static or permanent loads that connected with the weight of the structure and
this weight remains constant over time. The structural elements weight includes in the dead
load along with the partitions of permanents non-structural and the plasterboard as the
immovable fixtures (Designingbuildings, 2019). Dead loads used to calculate the weight by
accessing the specific materials. It is also possible to calculate the dead loads with a good
degree of accuracy. Dead loads with the structural engineers are estimates constructive.
Safety for imposed load:
Imposed load area the applied load on building and streets that arise for the purpose of building
of service life. The value of the imposed loads categorises into the section as per the values of
floor and structure. This kind of load is not the permanent load and can change as per the load
capacity with the distraction rate (Bd.gov, 2011).

capacity with the distraction rate (Bd.gov, 2011).
Building regulation and Code of practice:
The design structure of the material is responsible for the code of practice for live loads. The
surface rate changes the applied load with the deformation of the applied structure and this
process related to the material of the load structure. The deformation rate of the part of the
material is low and this occurs on the safety factor on the time with the design structure of the
material. The complete weight of the structure depends on the dead load application that used to
build the depending regulation. The code of practice that relates to the dead load depends on the
structural panel with the basic design.

Q. 5. Define the following:
(a). Young’s modulus:
The Young's modulus is used to measure the resistance and stiffness of a solid with the elastic
deformation under the load. It relates to the stain and stress along with a line or an axis. Here
stress is the force per unit area and strain is the proportional deformation. The basic principle of
Young's modulus is, an elastic deformation undergoes on a material with it extend or
compressed when a force applied on it. The material returns into its normal shape when the load
or force removed. It can say:
A solid is in the elastic state when a low Young's modulus value appears
A solid is inelastic or stiff when a high Young's modulus value appears
The equation of Young’s modulus is represented as:
E = σ / ε = (F/A) / (ΔL/L0) = FL0 / AΔL, in which
E is the young’s modulus that used to represent in Pascal (Pa)
σ is referred to as uniaxial stress & ε is refer to the strain
F is compression or extension force and A is the cross section perpendicular or the
surface area to the applied force
ΔL is the change of the length and L0 is the change in the length
The history of the young modulus defines by a Swiss scientist Leonhard Euler in 1927 and it
depends on the material orientation and the Isotropic material used to represent the mechanical
properties in the same direction (Helmenstine, 2018).

A type of geometric property used in the given cross section for the design of beams with the
flexural numbers. The other type of geometric property used in the design of the area with the
tension, gyration radius with the compression and stiffness of the moment of inertia. The
relationship of the section modulus depends on the shape in question as there are two types of

Q. 6. Elastic bending theory & find MOA for the following sections:
Elastic bending theory:
The material structure of an object is used to define with using the elastic bending theory that
works as an application. The material structure starts the capacity bending when the load
applied to the material by using the force capacity. The moment of bending increase as the load
increase on the material and on a certain period the material recovers its previous shape as the
force remove from the material. This process is known as the elasticity of the material. During
the process of the elasticity of the material, at one time the load increase with the time-bending
movement as high as its capacity and after removing the force or the load the material can’t get
its shape again. This process is known as the young modulus of elastic and this is the point of
the maximum bending position that found on the material (He, J. and Lilley, C.M., 2008).

Q. 8. Newton’s three laws of motion:
An object can’t move until an external force applies to it. It finds in a stationary state or the
mode. When force applies to the object is moved from one point to another. Here understands
Newton’s law of motion with different examples. A vector quantity that used to push or pull the
object is known as the force that used to interact with the objects. The force has different types
like balanced force and unbalances force.
The first low of motion is known as the law of inertia in which, each object remain in a position
or state until an external force applied to it. In the below picture an object (football) remains
constant until an act on it by the force of the human.
Figure 8: Newton's First low of motion
Source: (Blog.myran, 2017)
The Second law of motion states that the force is equal to the change in the momentum as per
the time change. That is defined as the F = ma where F is the force and m is the mass and a
denotes to the acceleration. In the below image of the example, a wagon pulls with using the
force and when the mass of the wagon increase than it is required to use more acceleration with
the force.
