Homework 05 Problem 1 The wing of the jet aircraft is subjected to thrust T from its engine and the resultant lift force . L If the mass of the wing is M and the mass center is at G , determine the x, y, z components of reaction where the wing is fixed to the fuselage at A . Given: m 7 m 3 m 5 m 5 . 2 Mg 1 . 2 kN 45 kN 8 = = = = = = = d c b a m L T Problem 2 The boom is supported by a ball-and-socket joint at A and a guy wire at B . If the loads kN 5 = F loads lie in a plane which is parallel to the x–y plane, determine the x , y , z components of reaction at A and the tension in the cable at B. Given: m 3 m 2 m 5 . 1 º 30 kN 5 = = = = = c b a F θ
