Holding the tube at an angle allows the air bubbles to escape. 6. Place the magnesium in the mouth of the gas collection tube so that it is about three cm below the surface of the water. Fold the thread extension over the side of the tube. Insert a one-hole stopper into the opening so that the magnesium

COMPOSITES COURSEWORK DESIGN AND ANALYSIS OF A LAMINATED COMPOSITE TUBE ABSTRACT This report details the process for the design of a composite laminate tube‚ the software package ’MathCAD’ was used to determine a lamina design with a configuration that avoids mechanical failure under loading conditions. It was also used to obtain twist angles and maximum stresses for specific lamina wind up angles. The report will provide analysis of the methods used to obtain these criteria. AIM Use a Mathcad

When I released that syringe‚ the second one would inflate. Therefore‚ I could accurately measure the amount of gas being produced. For the vinegar + ammonia test‚ I had the ammonia in the beaker‚ and I poured the vinegar into it. Similarly‚ for the hydrochloric acid + sodium hydroxide test‚ I had the sodium hydroxide in the beaker
