To determine the force acting on each mass it was assumed that g=9.80m/s². The value of g at the place where the experiment is performed may be slightly different from that value. State what effect (if any) it would have on the percentage error calculated for comparisons. To test your answer to the question, leave g as a symbol in the calculation of the percentage error. 2. Two forces are applied to the ring of a force table, one at an angle of 20.0, and the other at an angle of 80.0°. Regardless of the magnitudes of the forces, choose the correct response below. The equilibrant will be in the (a) first quadrant; (b) second quadrant; (c) third quadrant; (d) fourth quadrant; (e) cannot tell which quadrant from the available information. The resultant will be in the (a) first quadrant; (b) second quadrant; (c) third quadrant; (d) fourth quadrant; (e) cannot tell which quadrant from the available information. 3. Two forces, one of magnitude 2 N and the other of magnitude 3 N, are applied to the ring of a force table. The directions of both forces are unknown. Which best describes the limitations on R, the resultant? Explain carefully the basis for your answer. (a) R55N (b) 2 NSRS3N (c) RX3N (d) 1 NSR55N (e) RS2N 2013 Cengage Leaming. All Rights Reserved.

Suppose the same masses are used for a force table experiment as were used in Part 1, but each pulley is moved 180 so that the 0.100 kg mass acts at 200, and the 0.200 kg mass acts at 270°. What is the magnitude of the resultant in this case? How does it compare to the resultant in Part 12 5. Pulleys introduce a possible source of error because of their possible friction. Given that they are a source of error, why are the pulleys used at all? What is the function of the pulleys? Copyright 2012 Copa Learning. All lights Reserved.

You can discuss among yourselves what's needed and the generally approach to solving a problem(s). Under no circumstances are you to allow another student to look at your work/lab report, or copy from it (in part or in it's entirety). The only absolute similarities between group members should be group data. #1 Lab Rule: Do NOT show your work, lab manual report, or calculations to anyone! You have been warned... Full lab manual document submission for 205 S104 1. Complete lab report material for lab: "Force Table, Vector Addition (chap. 3)" Due on Tuesday 06/20/17 ) a) Make sure the name, section number, date and lab partners entry is filled out. V b) Make sure Data & Calculations (Graphical & Analytical) Table 1 is completed. V c) Make sure the four (4) calculations of Part 1 - Error Calculations is done. Please show these simple calculations on a separate page if need be. V d) Please submit the graphical solution page as well. One drawing page per group. However, every student has to submit their own completed lab material. ✓ e) Answer post-lab questions 2, 3, 4 & 5 only. V Other relevant information. 1. Side Note: The next lab on the lab schedule is: "Newton's 2nd Law: Atwood's Machine". I. I will give you all lab documentation for this next lab. II. Therefore, there is NO pre-lab for this next lab. Additional note(s) on completing this lab: 1. DO NOT DO anything that deals with Part 2 (3 vectors). V 2. As an example: Abs. Err. = 8exp. - Canaly 3. You should do sample calculation(s) where needed (analytical/trigonometric calculations etc.), so that I can see that you understand the mathematical process. Neatness and finesse is always appreciated. LET ME KNOW IF YOU ALL HAVE ANY OTHER QUESTIONS: Click here to send me an email (Prof. A. Johnson)
