Unformatted text preview: PROBLEM 4.6.9 GOAL : To determine (a) the resultant force in vector notation in the xy coordinates, (b) the resultant force in vector notation in the x y coordinates, (c) that || T R || = || T R || GIVEN : Figure E.4.6.9. ASSUME : Planar. DRAW : FORMULATE EQUATIONS and SOLVE : T R = 150 N(cos 100 i + sin 100 j ) + 200 N(cos 15 i + sin 15 ) j ) = (167 . 138 i + 199 . 485 j ) N RESULTS (a): T R = (167 . 1 i + 199 . 5 j ) N FORMULATE EQUATIONS and SOLVE (b): T R = 150 N(cos 120 i + sin 120 j ) + 200 N(cos 35 i + sin 35 j ) = (88 . 830 i + 244 . 619 j ) N RESULTS (b): T R = (88 . 8 i + 244 . 6 j ) N FORMULATE EQUATIONS and SOLVE (c): || T R || = (167 . 138 N) 2 + (199 . 485 N) 2 = 260 . 249 N || T R || = (88 . 830 N) 2 + (244 . 619 N) 2 = 260 . 248 N RESULTS (c): || T R || = || T R || CHECK : Part (c) forms a good self-check....
