Fix the launcher so its angle of launch θ is zero degrees. Use your level or your angle inclinometer to make sure the angle is correct. 8. Suspend a plumb bob so that it just touches the floor directly below the point where the ball leaves the launcher (which is marked on the launcher). Mark this spot on the floor with tape.
Newton’s Second Law Lab Purpose: The purpose of this experiment was to determine the relationships between mass, force and acceleration as well as to prove Newton’s second law Hypothesis: It was hypothesized that there would be an inverse relationship between acceleration and mass; as the value of the mass increased the acceleration decreased. As well it is hypothesized that there would be a direct relationship between the net force and acceleration; as the net force increases the acceleration increases as well. Materials & Method: The materials that were required to do the experiment were a metre stick; its purpose was to measure the amount of string that is going to be used to drag the cart. Next equipment needed for the lab was a dynamic cart; it was going to be dragged by the string with a mass on the other end and will find relationships between these two. Also string (about 75cm) was needed in this experiment which would help pull the cart with the help of the masses that were used.
Density Lab Report Objective: To measure the density of different materials. Materials: 400 mL Beaker Ruler Water Triple Beam Balance Box of Density Cubes Goggles Tongs Procedure: 1. Put on all safety equipment and gather all materials. 2. Create a chart (A) in your data section with three columns.
Determination of “g” by the use of a Pendulum This experiment is going to utilize a bob on the end of a string line to determine the value of little “g” by measuring the length of the string and the duration of time it takes for the bob to swing from one fulcrum point back to the same point after swinging 10 times. The justification for the bob swinging 10 times is to generate a more accurate measurement of time. To start the supplies that are required for this experiment are a stable stand for the string to be secured to. A minimum of a two yard line of string to that can be secured to the anchor and a bob and obviously a bob to be attached to the end of the string. We also need a stopwatch to measure the time duration and a measuring tool to determine the length of each experiment.
1) Draw and cut square specimens with dimensions 15x15 cm from the prepeg roll. 2) On the left side of the mould, place the first prepreg layer with the fibers parallel to the short dimension of the mould. This will be the zero-degree orientation. 3) Place three additional layers following the stacking sequence 90/90/0. This completes a 4 layer symmetrical laminate
2. On one end, attach the “weight bucket” 3. Tape the other end to the top of your table so that it is 65cm of string from the table to the part attached to the top of the “weight bucket”. (See the image on front for the set-up) 4. Place a 10g weight in the “weight bucket”.
Make sure the balance also reads 0.00 g. If not tare the balance prior to massing. 4) Place the beaker with water and a half of the tablet on the balance. Record the mass in the appropriate box in the data table. 5) Return the beaker and tablet from the pan. Return to your place with the beaker and the tablet.
Introduction Machines usually operate at a fixed speed and exhibit vibration, so the machines will generally be excited at a fixed frequency which is sometimes the operating frequencies or other fixed frequencies which are proportional to the driving speed. When the machines have run over a long period or been installed in undesirable boundary conditions, the vibration amplitude of the machines may rise and reach some pre-defined vibration levels in accordance with the safety regulations or comfort criteria. In order to reduce the response amplitude in these cases, remedial work is applied. Many solutions are found to solve the vibration problems in the machines
