Repeat this at the same setting 1 more time to find an average. At the same angle, choose a second setting of force and repeat the process. Follow this procedure using different angles.

4.1.1. The system must load the coupon into it database if the coupon is not

The Effects of Nitrogen and Phosphorus Enrichment on Water Samples from Encanto Lake and the Rio Salado River.

Hold one ball beside the top of the meter stick with the ZERO end touching the table.

Environmental scanning can be viewed as a way of acquiring information about outside events that can aid organizations in first identifying potential trends, then interpreting them

Those who take the time to post match-ups will almost always tell you the source and date of the coupon. That makes it easy to go to the correct file and cut the coupons you need for that week's shopping trip.

Using Gravitational Force as a Measurement Tool Answer the following questions about the results of this activity. Record your answers in the boxes. Send your completed lab report to your instructor. Dont forget to save your lab report to your computer Activity 1 Record your data from Activity 1 in the boxes below. Enter the data for the sample you used in each trial (5000 rpm, 10000 rpm, etc) in the appropriate columns and the corresponding g-force, number of layers, and position of layers position results. You will need to use the following formula to assist with your laboratory report G-force 0 00001118 x radius of centrifuge arm x (rpm)2 The radius of the centrifuge arm for this instrument is 10 cm. Speed 5000 rpm 10000 rpm 15000 rpm

The specimen ends were not thick or had moving wedge grips to keep it secure in the holders of the servo-hydraulic load frame. The movement of the specimen in the machine causes some of the data to be an inaccuracy. Also, the transverse strain causes issues with the strain gages that are called transverse sensitivity. The transverse sensitivity affects the accuracy of the data that is being collected for the transverse strain more than the longitudinal strain. This is greatly seen in the percent difference in the strain values such as in one case the Longitudinal strain was .4% while the transverse strain was 30%. Another issue with the strain gages was that if the strain gages weren’t properly placed on the specimen the data accuracy would

5. Record the effort force shown on the Newton Scale in newtons while pulling the cart up the inclined plane.

Loosen the retaining screw and adjust the horizontal arm to the dimple that produce the 2nd largest radius between the spinning mass and the rotating shift. Allow the spinning mass to hang straight down, without being connected to the spring. Position the pointer directly below the tip of spinning mass and secure the pointer to the base. Use the scale located on the base to determine the radius, r, of the pointer from the rotating shaft. Record this value onto Data Sheet A. The experimental uncertainty in r is estimated to be the width of the spinning mass tip – approximately 0.2 cm.

Measure the initial width, length, and thickness of the steel specimen using a Dial Caliper. Relieve pressure in Amatrol T9014 and adjust the height of the bottom platform to insert steel specimen. Insert one pin into the bottom platform to hold the steel specimen into the fixture. Slide two locking bars down the steel specimen. Adhere one locking bar to the bottom of the specimen and one at the top, lock them in place using the attached thumb screws. Insert the Linear Vernier Caliper in the top locking bar and zero out the caliper, allowing it to rest on the bottom locking bar. Compress the hydraulic cylinder until the indicator reads a force of zero. Lock the Linear Vernier Caliper in place by tightening the top thumb screw. [1] Compress

· I set up the apparatus as shown in the diagram. I then placed a

Use a stopwatch to time 5 cycles and record the time in the data table.

Hold the test card away at an arm’s length and at eye level, while the other hand holds a yardstick just below the left eye. Put the test card on top of the meter stick. Make sure the cross on the test card is on the right hand side.

Below are two tables in which I have recorded the data which I obtained during the experiment. The first table reflects the Relationship between the deflection/flexion of the cantilever and the mass of the load and the second table reflects the relationship between the flexion of the cantilever and the length of the cantilever.
