The mold is placed into the machine. On one end of the machine there is a reciprocal screw in a heated barrel. The plastic is fed into the barrel‚ which in turn feeds it into the screw. The first section of the screw holds the plastic together so that it starts to melt. Moving a little further up‚ the threads on the screw become thinner.

What water bottle-designed car will travel the fastest? There are many factors that are important in determining the answer to this question. One is how much kinetic energy is needed to push the water bottle car forward. Also‚ Newton’s third law of motion tells how the air can push the car forward based on the force that the air from the balloon pushes backwards. Aerodynamics helps clarify how the air moves over the car and reduces the drag of the car. Overall‚ all of these factors play a part in

Due to so many variations of the functional morphologies of feeding‚ many studies have been conducted on wrasse feeding behavior to distinguish how the different modifications of morphology have become so diversified using the same basic mechanical (jaw) feeding system (Wainwright 1988; Westneat 1995; Hulsey and Wainwright 2002; Bshary 2003;
