The Stress-Strain Apparatus stretches (and in some cases breaks) a test coupon while it measures the
composites. Three tensile specimens and two bend test specimens were tested during this lab. The tensile specimens were a wet lay-up of bi-directional E-glass, and the bend specimens were made up of a nomex honeycomb core with pre-preg uni-carbon faces. The three tensile specimens were tested, their elastic modulus and ultimate tensile strength calculated, and these value were compared to published approximately equivalent material properties. The two bend test specimens were tested, their face bending
the event of pressing. A 2 mm thick 1000 series aluminum alloy sheet was considered. An elastic-plastic limited component model utilizing remeshing alternative was created. Tests were directed to confirm the dependability of the created limited component model. A critical clearance-thickness proportion which is a farthest point between two states of hole-flanging was discovered: hole-flanging with edge extending and hole-flanging with pressing in which the metal is crushed between the punch and the
the IR spectrum of 4-methylcyclohexene. What structural information can be obtained from these bands? - The C-H bonds in this structure are shown at 1444 and 1368cm-1. These two bands indicate the two different types of C-H bends that occur on the molecule. One is that of the alkene and the other is that of the several alkanes on the molecule. 5) 1-2 mL of saturated sodium chloride was used to transfer the
will be on three forms of material Brass, Copper and Aluminium. Each of the materials in order will be measured in their dimensional planes & material hardness determined before being processed through the laboratory cold rolling apparatus. Upon completion of the number of test trials the results found will be
In this article “Controlling the Work of Teachers” by Michael W. Apple. Apple believes, that teachers are doing more work because of the curriculum and that is not fair. The curriculum is designed by people who are paid and not educators. So, the creators of the curriculum has no idea of what it is like, to be a teacher. Making the designer of the curriculum be someone who has a true interest in education, would help improve the learning environment. Those being in control of the curriculum
Scuba diving is diving with a self-contained underwater breathing apparatus, that is completely independent of surface supply. Providing the diver with the advantages of underwater mobility whilst being able to sustain life at underwater pressures. Embolism results when gasses in the lung expand during ascent and rupture lung tissue, causing air bubbles to enter the bloodstream. The Usage of
Results The experiment performed included the use of sodium hypochlorite (bleach) to oxidize an unknown secondary alcohol and the determination of the identity of the alcohol and the ketone product by IR spectroscopy. To begin the experiment, approximately 1.75 g of the assigned alcohol, unknown D, was added to a 50 mL Erlenmeyer flask along with 1 mL of acetic acid. After 15 mL of household bleach were dispensed into a graduated cylinder, it was added in small increments with a pipette to the alcohol
Have you ever wonder if plants have intellect? Although plants have no brains there are reasons to believe that plants can communicate, measure time, recognise related plants, and have memory. If these theories that plants were to have intelligence were proven whole new doors could swing open for scientists, and could change views on evolution and change the views on the world and its plants. Science could look deeper into how beings have intelligence without a brain, and the human race could expand
The Effect on the Rate of Respiration of Yeast Cells with Glucose when the Temperature is Varied Aim The aim of the experiment is to investigate the effect of temperature on the rate of respiration of yeast cells with glucose. As yeast cells use up glucose in respiration, carbon dioxide gas is given off. Measurements of the volume of carbon dioxide gas given off within a set amount of time can be used to measure the rate of reaction. A fast rate of reaction would
