CIVE 210 Homework 2, Spring 2011

*2-32, In each case resolve the force into x and y components. Report the results using Cartesian vector notation. (b) F=101b i) *2-36. Determine the magnitude of the resultant force and its direction measured counterclockwise from the positive .x axis. *2-56. Three forces act on the bracket. Determine the magnitude and direction 6 of F, so that the resultant force is directed along the positive x’ axis and has a magnitude of 800 N. Civé 210 HOMEWOR< 7) C "2-88. The positions of point 4 on the building and point 8 on the antenna have been measured reiative to the electronic distance meter (EDM) at O. Determine the distance between A and 3. Hint: Formulate a positon vector directed irom 4 to 8: then determine its magnitude. 2-100. The antenna tower is supported by three cables. If the forces in these cables are Fg = 320 N. Fe = 680 N. and Fp = 560 N, determine the magnitude and direction of the resultant force acting at A. *2-108. The chandelier is supported bv three chains ‘yhich are concurrent at point 2. If the resultant force at z O has 2 magnitude of 130 Ib and is directed along the negative < axis, determine the force in each chain assuming F, = Fg = Fe.
