3. Set the launcher to launch horizontally. 4. Load the Launcher to the Medium range at the first click. Take 2 test runs and then tape a piece of white paper on the floor and put the carbon paper on top of it.
3. Put the first mass on the spring and wait until it stops bouncing 4. Measure the weight on the ruler and record it in the data table 5. Put the second mass on the spring and wait until it stops bouncing 6. Measure the weight on the ruler and record it in the data table 7.
The dynamic strength test tests your upper body strength. Equipment used is called the ‘Dyno’. (Back strength test) You have to sit with your chest resting against the padding, grab hold of the handle and pull until your hands are level with your sternum. You’re allowed 3 warm up attempts and then you have five full pulls and the averages of all 5 pulls are recorded. The pass rate for this test is to be able to pull 35KG.
We took a yardstick and support it on both ends. Then we took a second yard stick and placed it next to the yard stick that was flat to facilitate a reference point to measure the displacement of the no load situation and subsequent measurements with different load weights. From here we added a known quantity of weight in the center of the yardstick and measured the displacement from the second yard stick. We completed five measurements increasing the weight in the center of the yardstick and measuring the displacement without reaching the breaking point. A diagram of the experiment is shown below.
Which of the following diagrams best represents the directions of the actual forces acting on the box as it moves upward after the push? 3. An ideal spring obeys Hooke's law, F = kx. A mass of 0.50 kilogram hung vertically from this spring stretches the spring 0.075 meter. The value of the force constant for the spring is most nearly (A) 0.33 N/m (B) 0.66 N/m (C) 6.6 N/m (D) 33 N/m (E) 66 N/m 4.
Projectile Motion Internal Assessment BY: Abel Giday Date: November 19, 2010 Design: Marble Direction of Marble Two Meter Sticks on Inclined Plain (to help direct marble) Photo Gate White Paper Inclined Plain Carbon Paper Table Table Hanging Weight Meter Stick Weighing Scale Plastic Bag and Stand (To capture Marble) Caliper The above diagram represents a method that can be used in order to investigate, Projectile motion. As the marble is released from a specific height on the inclined plane, two parallel meter sticks help guide the marble directly down the ramp. As the marble is rolling down the ramp with a certain velocity, it crosses through the Photo Gate which allows one to obtain an accurate reading of the marbles instantaneous velocity. The marble then drops of the table and falls to the ground due to the influence of gravity. As it hits the ground it lands on carbon paper that has been placed over another blank piece of A4 paper.
Place a 10g weight in the “weight bucket”. 5. Pull the string to a 20O angle on the protractor. 6. Using a stopwatch, carefully time 1 period (from A to C to A on the image on front).
We moved around the weights until we ended up with what we saw to be an even leveled meter. We repeated this a second time using two slightly different weights and recorded them. Our third trial was done in a slightly different way, instead of having a single weight on each side, we placed two masses on the right side of the meter stick and only one on the left. Again, we played with the weights until we were at equilibrium and recorded our data. The second half of the experiment was done in a similar fashion, except the ruler was no longer hung on
The objective of this investigation is therefore to establish a relationship between the length of a cantilever and its deflection in the aforementioned situation, which may give some insight into the physics of cantilevers. Variables The independent variable in this investigation is the length of the cantilever in meters. This will be varied by changing the length of the yardstick functioning as a cantilever that extends over the edge of a table. It will be measured indirectly by measuring the length of the portion of the yardstick not in use and subtracting that from the entire length of the yardstick. The dependent variable in this investigation is the deflection of the cantilever in meters.

These material properties include the following: the elastic modulus, 0.2% offset yield strength, ultimate tensile strength, modulus of rupture, modulus of resilience, as well as true strain and true stress at the point of rupture. Theory: Certain materials (those that are linear, homogeneous, elastic, and
