BASIC CONCEPTS OF STATICS

Statics is a branch of Engineering Mechanics which deals with the effects of external forces applied to rigid forces. The basic concepts continue from discussions in Physics thus the types of quantities are the starting point of lecture.

THEORY OF STRUCTURES COURSE OUTLINE

Theory of Structures is the preliminary load analysis before designing a structure. In this course,  students should be able to determine the internal forces, each member in the structure is handling.

Topics for the course are as follows:

• Introduction
• Basic Concepts
• Determinacy of Structures

FLUID MECHANICS LABORATORY MANUAL

Each student is required to have a copy of the laboratory manual. The experiments can be downloaded individually as the class progresses, but individual reports and research works would be compiled and submitted at the end of the course.

• Cover page
• Introduction
• Research work 01: Laboratory Familiarization
• Experiment 01: Specific Gravity of Fluids
• Experiment 02: Unit Weight and Archimedes' Principle
• Experiment 03: Viscosity of Fluids
• Experiment 04: Pressure on a Submerged Plane Surface
• Experiment 05: Pressure Measurement Using Manometers
• Experiment 06: Reynold's Number: Laminar and Turbulent Flow

CONCEPT OF STRESS

It is quite complicated to determine the strength of each material used in the engineering field. Although the principle is simple as to learn the exact amount of load a particular material can handle or withstand, parameters leading to the identification of this is difficult to attain.

In order to do this, engineering stress is used to determine the strength of materials. Stress as defined is the ratio of the force applied to the material at its cross sectional area. Different kinds of stress have been analyzed although most of the time, load transfer is just a minor alteration to the formula. The more critical parameter to analyze is the cross-sectional area on where the force is applied, which usually depends on which kind of stress is being studied.

CONCEPT OF STRAIN

Strain is another design parameter used to determine the strength of a material. This is defined as the change of elongation to the original length of the material. 

Although this parameter will lead the designer to the actual load a material can handle, using strain in computations would need the size and shape of a material. Thus the use of the stress-strain diagram. The stress-strain diagram will give the designer the loading handled by a material without using shape and size; meaning this diagram is constant to a material.

There are different parts of this diagram but the engineers are only limited to use the proportional area or that area before the elastic limit. From its name proportional area would show that the change in stress is proportion to the change in strain. And as it does not exceed the elastic limit, this is the area where materials are still able to return to their original length or size when they are unloaded.
