Engineering

An aerospace engineering company has designed a glass pod that can be attached to existing aircraft. This pod has two seats and allows passengers to enjoy a 360-degree view during the flight.

We embrace the exponentially curious mind, thinkers who see engineering and logic in everything, people that dream and do. Come and join our team of engineers.

How a Spider Produces a Web🕸️ 1. Silk Glands and Spinnerets🕸️ - Spiders have specialized glands, called silk glands, located in their abdomen. These glands produce liquid silk protein. - The liquid silk travels through ducts to the spinnerets, small organs at the rear of the spider's abdomen. Spiders can have between two to eight spinnerets, depending on the species. 2. Silk Production🕸️ - When a spider is ready to spin a web, it extrudes the liquid silk through tiny spigots on the spinnerets. As this liquid hits the air, it hardens into a solid thread due to the interaction with air or due to chemical changes within the silk itself. 3. Web Building🕸️ - Frame Threads: The spider first lays down anchor threads or "bridging lines" between secure points, like branches or leaves, to form the frame of the web. - Radial Threads: From the center or hub, radial lines are extended outward connecting to the frame threads. - Spiral Threads: A spiral of non-sticky or sticky silk (depending on the web type) is then woven between these radial lines, creating the capture area where insects get trapped. 4. Behavior and Strategy🕸️ - Spiders use their legs to handle and guide the silk, employing different techniques for different parts of the web. Some species recycle their webs by eating them to reuse the silk proteins, particularly in the morning. Details on Spider Silk‼️ - Composition🕸️ Spider silk is primarily composed of proteins called fibroin and sericin. Fibroin gives silk its strength, while sericin helps in sticking the silk together. - Types of Silk🕸️ - Dragline Silk Used for the frame and radial threads, it's one of the strongest natural fibers known, with tensile strength comparable to steel of the same diameter but much more elastic. - Capture Spiral Silk Often covered in droplets of a sticky glue, this silk is designed to ensnare prey. - Egg Case Silk Thicker and tougher, providing protection for spider eggs. - Cribellate Silk Produced by spiders without sticky silk glands, it uses fine, wool-like fibers that entangle prey through physical structure rather than stickiness. - Properties🕸️ - Strength Spider silk is renowned for its combination of strength, toughness, and elasticity. - Elasticity Some types of silk can stretch over five times their original length before breaking. - Biodegradability Spider silk is environmentally friendly as it decomposes naturally. - Applications🕸️ Due to its unique properties, scientists have been interested in mimicking spider silk for various applications, including: - Medical Uses For sutures, artificial tendons, or drug delivery systems. - Textiles For lightweight, durable clothing or protective gear. - Technical Applications In areas like bulletproof vests or biodegradable plastics. The complexity and efficiency of spider web construction, along with the extraordinary properties of spider silk, highlight the remarkable capabilities of these arachnids. Each spider species adapts its silk production and web-building strategy to its specific ecological niche‼️

And they just automatically know how to do it from birth

Spiderwebs are incredible feats of engineering! 🕸️ They're stronger than steel by weight! 💪 Nature is amazing! 🤩

Who thinks that bridge building engineers could learn a thing or two here?

Amazing. Then when you walk through it, you have the pleasure of tearing your shirt off, profusely beating your own head, screaming and running.

Blessed is the weaver

and hard work to survive…wonderful creatures but not in my house😏

I love engineering

So mesmerizing 😳 #zelena
