Strength of an uncooked spaghetti
Independent Variables: Typically the independent variable in this specific experiment was the known length of the bit of uncooked spaghetti. Dependent Parameters: In this experiment, the particular dependent variable was the volume of water added to the plastic mug suspended on the piece of uncooked spaghetti. Handled Variables: The controlled factors involved in this research were: the cross – sectional area of the spaghetti i. e. the same type of spaghetti was used meaning together with the same thickness in addition to the temperature where the particular experiment was conducted.
1. First We took two small dining tables and placed them parallel to each other. In that case using pieces of cello tape I clamped the particular two ends of any item of spaghetti of identified length to the a couple of tables. 2. Then We measured the mass of the plastic container used in the experiment. I attached two pieces of string to both sides of the container and rested it over the bit of spaghetti. 3. Then We filled the measuring tube with 25 cm3 regarding water and poured this into the plastic container. In case the piece of spaghetti did not break credited to this, I packed the measuring cylinder again and poured more water into the container.
4. I computed the volume of water added to the container prior to the spaghetti broke in addition to noted down my psychic readings. 5. All the above steps had been repeated for various measures of spaghettis i. e. 23 cm, 20 cm, 17 cm, 14 cm, 11 cm and 8 cm. 6. Thereafter, I carried out the computations needed using the above collected readings which are outlined in the right after pages. The length of the part of uncooked spaghetti has been varied by moving typically the small tables closer in order to or farther from each and every other, depending on what the particular span of the spaghetti had to be. Plus the length of typically the spaghetti used was assessed using a measuring tape.
The volume of water included with the plastic-type container resting on the part of uncooked spaghetti has been measured using a computing cylinder and then additional to the container. I actually made sure that my eye level was perpendicular to the mark in the scale towards which usually the lower meniscus of the water pointed. Considering that the same type of spaghetti utilized, the thickness we. e. the cross-sectional region of the spaghetti had been kept constant hence, not really affecting the readings attained. The temperature where all the experiments were conducted also remained constant in the room and this was made sure by constantly measuring the temperature of the room every 15 minutes plus noting down the temps.
