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

Isotonic uses your muscles to compress against an object with movement‚ like strength training. Stronger muscles‚ stronger bones and preventing injuries are just some of the benefits of isotonic exercises. Contracting your muscles against

■» 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

Powerlifting and CrossFit are both high intensity training methods in the US that combine for an annual income of 14 billion in 2015 alone. These sports have a training regimen that include free weights‚ increasing performance while gaining strength‚ as well as cardio vascular activity. Although both sports are based on athletes performing at high levels‚ the activities in which they engage in vary. Powerlifting for instance dates back as far as the Greek and Roman era which has allowed the sport
