pacing exercise

Introduction Pacing is one of the simplest methods of distance measurements. It consists of counting the number of steps or paces until the objective distance is acquired (i.e. determining the distance from one point to another). Using pacing as a technique in measuring distances has a relative precision of 1/200 or 1/100. It means that in every 200 or 100 paces, there could be one possible error, at the very least. However, one’s pace should be first calibrated to be able to have close approximation of the distance being measured. This calibration produces the “Pace Factor (PF) “, which is equal to the “Pre-determined distance” divided by the number of paces. Upon determining the PF, distance can be estimated by multiplying the number of paces and the pace factor. In the fieldwork undertaken at around five in the afternoon of June 27, 2013, pacing is the method used to determine the perimeter and area of the Old Engineering block, which runs through Roces St., Magsaysay Ave., Apacible St., and Osmena Ave. At that time, the weather had just cleared out after a rainfall which lasted about 10 minutes before the fieldwork is commenced. Procedure Before measuring the distance through pacing, the pace factor should be first determined. It is done by measuring 10 meters with any instrument such as steel tape and marking its endpoints with a chalk. Walk straight from one end to the other normally. While pacing, count the number of steps made before getting to the other end. If encountered with a fraction step, the count will be rounded up. Record the steps upon reaching the end. Repeat pacing 10 times and compute for the pace factor. After calibrating the steps, walk normally through the given endpoints while counting the steps being made. With the information collected, compute for the perimeter and area of the old Engineering block. Discussion 1 | Page

IntroductionPacng s one of the smpest methods of dstance measurements. It conssts of countng the number of steps or paces unt the ob|ectve dstance s acqured (.e. determnng the dstance from one pont to another). Usng pacng as a technque n measurng dstances has a reatve precson of 1/200 or 1/100. It means that n every 200 or 100 paces, there coud be one possbe error, at thevery east.However, ones pace shoud be rst cabrated to be abe to have cose approxmaton of the dstance beng measured. Ths cabraton produces the "Pace Factor (PF) ", whch s equa to the "Pre-determned dstance" dvded by the number of paces. Upon determnng the PF, dstance can be estmated by mutpyng the number of paces and the pace factor. In the edwork undertaken at around ve n the afternoon of |une 27, 2013, pacng s the method used to determne the permeter and area of the Od Engneerng bock, whch runs through Roces St., Magsaysay Ave.,Apacbe St., and Osmena Ave. At that tme, the weather had |ust ceared out after a ranfa whch asted about 10 mnutes before the edwork s commenced. ProcedureBefore measurng the dstance through pacng, the pace factor shoud be rst determned. It s done by measurng 10 meters wth any nstrument such as stee tape and markng ts endponts wth a chak. Wak straght from one end to the other normay. Whe pacng, count the number of steps made before gettngto the other end. If encountered wth a fracton step, the count w be rounded up. Record the steps upon reachng the end. Repeat pacng 10 tmes and compute for the pace factor. After cabratng the steps, wak normay through the gven endponts whe countng the steps beng made. Wth the nformaton coected, compute for the permeter and area of the od Engneerng bock.DiscussionThe number of steps from the cabraton and computaton of pace factor are the foowng: 16, 17, 17, 17, 16, 16, 16, 16, 18, and 17.Average PF=((5)10meters16steps+4( 10)17 +1018)10Average PF = 0.603 meters / stepThe number of steps made aong the Magsaysay Ave. s 316 steps.1 | P a g eDistance Magsaysay Ave. = (316 steps ) ( 0.603 meters/steps )Distance Magsaysay Ave. = 190.548 metersThe number of steps made aong the Apacbe St. s 218 steps.Distance Apacbe St. = (218steps ) ( 0.603 meters/steps )Distance Apacbe St. = 131.454 meters= 131 meters The number of steps made aong Osmena Ave. s 316 steps.Distance Osmena Ave. = (316 steps ) ( 0.603 meters/steps )Distance Osmena Ave. = 190.548 metersThe number of steps made aong Roces St. s 217 steps.Distance Osmena Ave. = (217 steps ) ( 0.603 meters/steps )Distance Osmena Ave. = 130.851 meters= 131 meters To compute for the permeter, the dstances measured shoud be added. Perimeter = (2) 190.548 meters+ 130.851 meters+ 131.454 metersPerimeter = 643 .401 meters To compute for the area, the wdth s mutped wth the ength. Let the ength be equa to 190.548 meters and et the wdth be the average of 130.851 meters and 131.454 meters. Area = ((130.851+131.454)2)(190.548)Area = 24 990.85 m2 Durng the edwork, there are certan probems that mght have nuenced the resut of the measurement such as cars bockng the straght path of the dstance, dherent eevaton of sdewaks, condton of the body of the student, the speed of the pace, and the wetness of the road. ConclusionFrom the data coected, the computed permeter and area of the rectanguar od Engneerng bock through pacng, as a method of measurng dstances, are 643.401 meters and 24 990.85 square meters, respectvey. If the two computed vaues are to be compared wth the actua measurements, whch are acqured through the use of a more accurate measurng devce, the permeter and area shoud be cose to each other. Otherwse, the determned measurements are naccurate and/or erroneous. 2 | P a g e
