VectorsVECTORS: RESULTANTS AND COMPONENTSRev. 0Page 15CP-02Vector Terminology Summary+A resultant is a single vector that can replace two ormore vectors.+Components can be obtained for any two non-paralleldirections if the vectors are in the same plane.Restricting the treatment to perpendicular directionsand two dimensional space, the components of avector are the two vectors in the x and y (or east-west and north-south) directions which produce thesame effect as the original vector (or add to producethe original vector).+Components are determined from data, graphically oranalytically.F is calculated as follows:ysin = opposite/hypotenusesin = F /F or F = F sin y R y RF = F sin y RF = (80)(sin 220 )yoF = (80)(-0.6428)yF = -51 lbf at 90 or 51 lbf at 270yo oTherefore, the components for F are F = 61 at 180 and F = 51 lbf at 270 .R x yo oSummaryVector terminology is summarized below.
