A Report - Essay Example The eight chain model precisely exemplifies the supportive nature of system distortion at the same time calling for only two material constraints, an original modulus and restrictive chain extensibility. Due to the fact that these two constraints are mechanistically connected to the physical science of molecular network placement concerned with the distortion of rubber, the suggested model characterizes an unassuming and precise constitutive model of rubber distortion. The document also suggests that the network extension in this system model decreases to a figure that is the mean square root of the primary functional stretches due to efficiently sampling eight placements of primary stretch space. The outcomes of the suggested eight chain model and also those of a number of the noticeable models are likened to investigational data of Treloar exemplifying the dominance, straightforwardness and prognostic capability of the suggested model. Furthermore, a fresh set of tests and trials which bring out the state of distortion reliance of rubber is outlined and done on three materials made of rubber. This eight chain model is set up to model and forecast precisely the performance of the three tested rubber materials additionally approving its dominance and usefulness over previous reproductions.

A Beloved Place for the Rest, namely the Forest Essay

A Beloved Place for the Rest, namely the Forest - Essay Example Going to the forest is one of the best voyages in life to take. God indeed loves humanity as it manifests through the perfect beauty of the nature surrounding us. I can remember it was a sunny and blissful morning when I decided to take a trip to an outskirt nearby. Half a kilometer away, I could already tell that one blissful reunion would take place later that day. Because I am a forest addict, I had the cheek to go there all by myself. Just like what most forest goers encounter, I had my share of stern tests. Before I could get to the heart of the timberland, I knew, I had to go through some tough challenges. Finally, I arrived at the doorstep of the jungle. The first thing I saw was a cohort of vibrant buds bowing down their heads to welcome me. Although quite silly, I felt I was treated like a royalty. As I hovered above my head, I could see the wild vines meshing up with each other to form a lovely wild curtain; I could also hear the birds chirping tones in mirth. It seemed like they were chanting out in harmony to serenade me. I stared down and saw my leather booths muddled up with some thick mud clinging around them, but I knew the sludge was not going to stay there for long as the spikey fingers of the eyes were ready to wipe them out. When I finally took several steps inward, it seemed like the time has traveled so fast that day... the surroundings turned rather gloomy, although everything was still in sight. Different sounds I heard: the blabbing voice of the river, the squeaky and tiny sounds of the squirrels, the sound of the clapping leaves as they were swayed against each othe r by the wild winds, and some mysterious noises that blended together to create a perfect music – something that could not be produced even by the most brilliant record producers, composers, and singers. But of course it was not a walk-in-the-park trail; I also had some of the tensest feelings I have ever felt in my life. Who does not get scared by snakes? By scorpions and tarantulas?
