Unformatted text preview: .707 (734.958 N)  300 =  T => 819.615 N = T ____________________ Alternate math approach would be to simply subtract the two equations to solve since the coefficients for the R terms are the same. î terms: .707 R = T + 300 eq. (1) ĵ terms:  .707 R = 519.615 eq. (2) T = 819.615 Back substitute in eq. (1) to solve for R: .707 R = (819.615) + 300 R = 519.615 /  .707 = 734.958 = R Quiz2sp2006.doc 45 ° 30 ° A C B 600 N T pulls at A R Assumed direction F Begin with basics: R = ∑ F = T + F Define each vector in rectangular coordinates.
