CIV-100F Solutions Section B/E Fall 2011 Assignment 1 Due on Monday, September 19 th 2011 Draw a FBD if necessary; Pay attention to significant figures; A ruler is always required. 1- For the 160 kN force shown, determine its components with respect to the following axis: (a) x – y (b) x’ – y’ (c) e – f For (a) and (b), determine the solution algebraically (i.e. using i, j components). For (c), use graphic approach. Solution : (a) x-y kN R R X 1 . 131 35 cos = ° = kN R R Y 8 . 91 35 sin = ° = i kN R X ) 1 . 131 ( = j kN R Y ) 8 . 91 ( = (b) x’-y’ kN R R X 80 ) 35 25 cos( ' = ° + ° = kN R R Y 6 . 138 ) 35 25 sin( ' = ° + ° = i kN R X ) 80 ( ' = j kN R Y ) 6 . 138 ( ' = (c) e-f kN R R R e e 2 . 101 37 sin 108 sin = ° = ° kN R R R f f 5 . 96 35 sin 108 sin = ° = ° y R y x x R R R x ' R y R e f R e 160 kN 160 kN 35 º x y 160 kN 35 º x y y’ x’ 25 º y x ( e ) 35 º 18 º f
