 Engineering Drawing/graphic tools

Drawing is the language of engineers. Thousands (1000) of words cannot describe a part correctly which a single drawing represents accurately. Ideas of engineers are recorded by preparing a drawing, and execution of work is also carried out on basics of drawings. Communication of engineers is done with the help of drawings. Like music, drawing is an universal language of the engineering world.


Drawing instruments are used to prepare drawings easily and accurately. The accuracy of drawings depends on the quality of instruments. Desirable accuracy is only possible with quality instruments. It is therefore necessary to obtain the instruments of superior quality.

Earth vs Mars: A Simple Comparison of Gravity When we think about living on another planet, "one of the most important factors to consider is gravity" . Gravity affects everything—from how we walk to how our bodies function over time. In this blog post, we’ll explore the difference in gravity between Earth and Mars , and why it matters for space travel and future human colonization. Read More Our Solar system Earth vs Mars Is it time travel possible! Space-Time Fabric The Unity of the Universe 🌍 Gravity on Earth The gravity of Earth is what keeps us grounded—literally. It pulls everything toward the center of the planet, keeping our feet firmly on the ground. The standard gravitational force on Earth is: 9.81 meters per second squared (m/s²) This is also known as 1g , and it’s the reference point for gravity across the universe. 🔴 Gravity on Mars Mars, also known as the Red Planet, has much weaker gravity than Earth. The gravitational pull on M...
