Chapter 2 REVIEW OF RELATED LITERATURE AND STUDIES Related Literature Spider silk (Parasteatoda tepidarium) commonly known as agiw in Filipino‚is a material spun by varieties of spiders.Spider silk has a unique combination of mechanical strength and elasticity that makes it one of the toughest materials we know.(Arizona State University‚2013). Furthermore‚silk consists of very repetitive blocks of mainly glycine and alanine.These are the simplest and smallest amino acids allowing strands to be packed

Increased Muscle Tone and Strength Did you guys ever see a flabby dolphin or a weak-looking competitive swimmer? We didn’t think so. That’s because swimming is a great way to increase muscular strength and muscle tone -- especially compared to several other aerobic exercises. Take running‚ for example. When a jogger takes few laps around the track‚ that jogger

■» Marked by Teachers This document was downloaded from www.markedbyteachers.com Abstract The tensile test is widely used to provide basic design information on the strength of materials and as an acceptance test for the specification of materials. The teaching and learning of tensile testing was based on laboratory experiments used in the Mechanical Engineering Laboratory (CM180) at the City University. The experiment looked at how the microstructure of a material can affect its properties

Fig 1. SHIMADZU Tensile Strength Tester Machine. The data is collected in the sense of Applied Load (N) vs. Displacement (mm). Average Applied Load and Displacement from all five specimens is then used to calculate the Stress (MPa) and Strain. Stress/Strain

strong‚ light‚ and rustproof which is what makes it so important and diverse. The original application for this metal was in the military aerospace industry specifically because of its efficiencies in structural qualities‚ a result of titanium’s strength and density. It has become the metal of choice for many different applications. According to Titanium Industries‚ Inc.‚ Titanium was actually first used in dentistry in the 1940’s. Today titanium is routinely utilized in the dental industry for
