Introduction Drawing is universal language. It has several advantages over textual information. It is easily understood, - even by illiterates. Engineering drawing is the language of the technicians. Like any other language, engineering drawing has its rules and grammar. We must learn to use principles of engineering drawing to convey our ideas. It makes it possible to replicate the jobs in large numbers without any deviations. In this lesson, we are going to study basic rules of drawing. Drawing Basic Shapes 1)Triangle We can use compass and scale to draw triangle. Step #1: Take your ruler and a pencil and construct a segment of any length on a piece of paper as shown below Then, you will try to set your compass opening to match the length of segment AB Take your compass. Make your sure that the pencil is included in it. Put the needle of the compass at endpoint A and adjust your compass so that th...

INTRODUCTION: For me my project is not so easy because,there need to connect three phase connection.From starting only i am triying to do every prossible &impossible things on my project.I have made many diagram of my project because i have many  confusion regarding to connection of three phase and single phase.I as...

i make relay circuit for ganpati lighting. what things i use in this circuti. 1)relay circuit 2)diode            3)transistor  4)1k ohms  5)10k ohms     and my circut is complited.

*Shuwas sir gave us all the materials for the circuit. *We one by one started to solder the components on cuircuit. *Sir give us the diagram of the circuit by which we understand properly. *We used small solder gun because the circuit is very small and also the component are tiny. Materials: 1)Copper plate circuit. 2)Led's. 3)Button cell. 4)Resistors. TOOLS: 1)Soldering gun. 2)soldering wire. 3)Multimeter. 4)Stripper. PHOTO'S:

MATERIALS:- LM 317 Resistor Veriable resistor Ciramic capasitor Circuit diagram PROBLEMS WHILE MAKING-1)I not  place a resostor for  the veriable resistor for that veriable resistor is burn fully .soo i change the veriable resistor but with that i place a resistor of 1K. 2)Due to unavaibleity of ciramic capasitor i not use ciramic capasitor.so it give me a huge problem while making. OBSERVATION- The LM317T is an adjustable 3-terminal positive voltage regulator capable of supplying different DC voltage outputs other than the fixed voltage power supply of +5 or +12 volts, or as a variable output voltage from a few volts up to some maximum value all with currents of about 1.5 amperes.                                                                        ...
