HOW DOES THE MOON CAUSES THE TIDES IN THE OCEAN?

The ocean is never still. Whether observing from the beach or a boat, we expect to see waves on the horizon. Waves are created by energy passing through water, causing it to move in a circular motion. However, water does not actually travel in waves. Waves transmit energy, not water, across the ocean and if not obstructed by anything, they have the potential to travel across an entire ocean basin.            Waves are most commonly caused by wind. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest. These types of waves are found globally across the open ocean and along the coast.             More potentially hazardous waves can be caused by severe weather, like a hurricane. The strong winds and pressure from this type of severe storm causes storm...

TOOLS USED FOR CARPENTRY….

WOODEN JACK PLANE : A wooden jack plane is the common test and is used for the first turning of a piece of wood it consists of a block of a wood into which the blade is firmed by a wooden wedge . IRON JACK PLANE : A iron jack plane serve the same purpose as the wooden planes bt faciliate a smoother operation and better finish.. TRY SQUARE : Try square is used for making and testing angles of 90. It consists of a steel blade viveted into a hard wood stock which has a protective brass plate. BEVEL SQUARE : The bevel square is similar to the try square but has a blade that may be switched to any angle from 0 to 180. This tool is adjusted, by releasing with a turn screw. MARKING GAUGE : The marking gauge has one marking point. It gives an accurate cut line parallel to the true edge. Usually with the grain. CROSS CUT SAW : A crosscut saw (thwart saw) is...

CARPENTRY WORKSHOP

CARPENTRY WORKSHOP

INTRODUCTION : Carpentry is the process of any class of work with wood. Carpentry deals with all works of a carpentry such as making of furnitures, doors, windows, floors, partitions and interior decoration etc, timber is the basic material used for any class of wood. The term timber is applied to the trees which provides us with wood. Types of wood most commonly used for various woods are as follows : TYPES OF TIMBER : Teak wood Assam teak wood Rubber teak wood Mango wood Sal wood Babul wood TYPES OF CARPENTRY TOOLS : Iron jack plate 14" Steel plate 24" Try square 6" Rip saw 18" Hand saw 12" Tenon saw 12" Frimer Cchisel 25 ,18 ,12 ,6 mm Berel edge chisel 18 ,12 mm mortise chisel 12mm Alumminium marking gauge and mortise 2" * 2" Marking gauge 2" * 2" Pincer 2" * 2" Claw hammer Wodden mallet 4" * 4" Carpentry Vice 8" * 8" To know the applications and uses the above tools click...

WATER AND ITS TREATMENT

WATER AND ITS TREATMENT

INTRODUCTION : Like air water is one of the basic materials which is of prime importance for the preservation of life on this earth. All are aware of the uses of water drinking, cooking, bathing and farming etc. , but few know the importance of water as an engineering material. As an engineering material water is used to produce steam in boilers to generate hydro electric power, furnishing steam for engines, for refrigeration and air conditioning, for construction of concrete structures for manufacturing purposes and as a solvent in chemical process. Hence an engineer should posses knowledge regarding the composition, troubles that arise due to composition of water and prevention of these troubles. OCCURRENCE : Water is widely distributed in nature. It has been estimated that about 75% matter on earth's surface consists of water. Besides visible water on earth, there is a large amount of water under earth to an average SOURCES OF WATER : THE MAIN SOURCES OF NATRAL WATER ARE FOLLOWING...

SOURCES OF WATER – RAIN WATER

SOURCES OF WATER – RAIN WATER

RAIN WATER : Rain water is the most important sources of water and the purest from of natral water. It is naurally distilled water as the water from sea, rivers etc. , first evaporates in the great heat of sun to form clouds which afterwards condense and water comes down in the form of rain. As the rain water falls on the surface of the earth and flows as streams or seep through through earth's crust, it takes up dust particles, oxygen, carbon dioxide, nitrogen and other dissolved and suspended solids present in the atmosphere and solid.  ...

TYPES OF BEAM

TYPES OF BEAM

FIRSTLY WHAT IS A BEAM ? In a structure, horizontal member which takes transverse load (load parpendicular to the length of the beam) in addition to other loading is called BEAM. In engineering structures like bridges, beam is one of the important structural member. In trusses and frames, pin-joined members take only tensile or compressive load, twisting load, etc., to take all types of load, i.e transverse load, tensile load, compressive load, twisting load, etc,. CLASSIFICATION OF BEAMS : Beams are classifed depending upon the type of support, as shown below: SIMPLY SUPPORTED BEAM: As the name indicates, it is simplest of all the beams which is supported by a hing at one end a roller at other end. SIMPLY SUPPORTED BEAM WITH OVERHANG: Here, one end or both ends of simply supported beam is projected beyond the suports, which means that the portion of beam extends beyond the hinge and roller supports. CANTILEVER BEAM: A beam which is fixed at one end and free at other end...

SYSTEM OF FORCES

SYSTEM OF FORCES

System of forces is a simple term defined to a group of forces. It can be classified into following types  Collinear Forces : The forces which are passing leniarly are called colliner forces. Non - Collinear Forces : The forces which are not passing in leniarly are called Non - collinear forces. Co - Planer Forces  : In this the forces are passing through the same plane. Non - Coplaner Forces :  These forces do not move in a same plane. Concurrent Forces : The forces which are passing through the same point. Non - Concurrent Forces : The forces which donot passes through same point. Non - Coplaner Non - Concurrent Forces : The forces which does not passes through the same plane and same point. Non - Coplaner Concurrent Forces : The forces which does not passes through the same plane but meetiong at one point. ...

FORCE

FORCE

What is force actually.... Force is defined as an agent which produces or tends to produce; destroying or tends to destroy the motion of a body Units of force is newton (N) . ---> A force while acting on the body may change the motion of a body, rise to the internal stress in a body  (N/m^2). Force is a vector quantity. Force is used to indecate a force, a torque, a moment etc. Lets move on to SYSTEM OF FORCES......
