Objective
The primary objective of this study is to determine the overall value of flexural strength, flexural
modulus as well as the maximum flexural strain of the material. This analysis mainly appraises at
least five beams and these includes 2 timber beams 2 reinforced concrete (RC) beams as well
as 1 steel beam.
Introduction
In essence, this mechanical lab work mainly used to measure and determine the materials
behaviors when they subjected to the parametric bending loads. Flexural modulus or stiffness of
the material mainly computed from the being load against deflection curve slope. Furthermore, it
is important to note that flexural bending mainly incorporates the material bending rather than
just focusing on the pulling and pushing impacts (Kang et al. 2014). This is often used in
computing the existing relationship between the overall deflection and the bending in the
material. Additionally, it is essential to establish and report that flexural testing mainly used to
handle the brittle materials and some of these primarily include stones, masonry, glasses as well
as ceramics. Subsequently, the concept of the makeable three points mainly used in developing
the bending flexural test and they help in providing the elasticity modulus in line with the
flexural bending, strain as well as stress. In essence, the three pint method tends to have
advantages more so when one is dealing with the specimen preparations as well as the testing.
Conversely, the method main have imminent disadvantages when one is dealing with it. The
disadvantages mainly include sensitive recorded on the loading geometry and the specimen stain
rate. The analysis for the three point testing method mainly illustrated as shown in the figure
below (Disfani et al. 2014 p.667).

Notably, the flexural stress often computed using the equation indicated below in line with the
load deflection (Uzel et al. 2018 p.149).
On the other hand, the flexural stress mainly defined as the ratio of the material maximum
capacity to the overall plastic deformation resistance which the material can accommodate. The
equation regarding the analysis mainly depicted as indicated below (Hauser and Wang 2018 p.3).

Conversely, the flexural strain mainly demarcated as the nominal fractional variation in the
parametric length in the pertinent specimen outer surface. The values mainly recorded in line
with the middle span space and at the denoted point where the maximum strains is likely to
occur.
Subsequently, elasticity modulus refers to the ration of the overall stresses to the elementary and
corresponding strain recorded within the parametric elastic limit (Hao et al. 2015).
Method
The method used in the analysis mainly incorporates the following steps
 Measuring the beam width as well as the overall thickness
