PART I - INTRODUCTION 
1. The general target of experiments of the subject 
Strength of materials as a basic subject in engineering field is defined as a branch of 
mechanics of deformable solids that deals with the behaviours of solid bodies subjected to 
various types of loadings. It provides the future civil engineers with the means of analyzing 
and designing so that all types of structures operate safely. 
The method to study Strength of materials is association between theory and 
experiments. The study by experiments not only decreases or replaces some complicated 
calculations but also raises assumptions to establish formulas and checks the accuracy of the 
results found by theory. 
The laboratory manual of Strength of materials is compiled in order to instruct 
students the most basic experiments of the subject. Hence, it helps students to get used to 
research method relying on experiments and understand the importance of experiments in 
study. 
2. General introduction about equipment in the laboratory 
The laboratory of Strength of materials has: versatilely tensile (compressive) machine, 
tensile (compressive) machine FM1000, torsion testing machine K5, two fatigue testing 
machines, two impact testing machines, deflection of string measuring machine, torsion 
testing table, plane bending testing table, axial compression testing table. Besides, there are 
measuring equipments: calipers, ruler, steel cutting pliers 
3. Progress and time to deploy experiments 
 After finishing the chapter “Torsion in round shaft”, students start experimenting the 
first three lessons. After finishing the chapter “Buckling of columns”, students experiment the 
last two lessons. 
4. The assessment of the experimental results of students 
 The experimental results of students are assessed by answering questions in class, 
observing students during the process of experiments and checking reports. 
5. The preparation of students 
Before experimenting, students have to carefully study experiments. The leader of 
class prepares list of students, divide students into small groups and sends it to lecturer two 
weeks before experiments.

1.Thepurpose of experiment: 
 Determine the deflection and slope of the straight bar subjected to planely horizontal 
flexure by experiments. Hence, we can evaluate the accuracy of the deflection and slope

2. Theoretical content 
 To determine the deflection and slope of the beam subjected to planely horizontal 
flexure, we have the following methods:

 - Morh’s integration method associated with multiplying Veresaghin’s diagram. 
Use Morh’s integration method associated with multiplying Veresaghin’s diagram to calculate 
the deflection at B and the slope at A for the simple beam subjected to loads as in the figure 7. 
It is carried out by the following steps: 
 - Draw diagram Mx

1.Thepurpose of experiment: 
Determine critical load by experiments and observe the stability of the column

critical load by theory. 
2. Theoretical content 
 Assume that there is the bar subjected to axial compressive load. The bar will be lost 
its stability as compressive load reaches critical load or compressive load is larger than critical 
load. Critical load is determined by Euler’s formula:
