Unformatted text preview: Questinn l The 20—kg ﬂowerpot is suspended from three wires and supported by the hooks at B and C. The angle between cord A C and A D is 126.90? and the angle between cord AB and AD is 143.1 ‘1 Using equations of equilibrium, determine the tension in cords AB and A C for equilibrium. ’s=- CR i w: games: we; iv’ 9 “V, Z'de? 2:) TAB) C05 63.x“ - TM Cogeéﬁ e 0 Q9 Question 2: The hood of the automobile is supported by the strut AB, which exerts a force F: 24 {b on the hood. The hood is hinged along the y—axis. The coordinates of points A and B are (4,0,0) and (2,2,4) ft, respectively. 3) Express the force Fusing Cartesian vector notation. b) Determine the moment of the force F about the hinged axis y.
