2.8 FORCE VECTOR DIRECTED ALONG A LINE 67 *2-96. The three supporting cables exert the forces shown on the sign. Represent each force as a Cartesian vector. 2-97. Determine the magnitude and coordinate direction angles of the resultant force of the two forces acting on the sign at point A. Z 2-99. The load at A creates a force of 60 lb in wire AB. Express this force as a Cartesian vector acting on A and directed toward B as shown. 2 c 2 m Copyright B E 2 m FE= 350 N Fc= 400 N 1 3 m FB = 400 N 130° 5 ft- y 10 ft A 1 A F = 60 lb 2 m 3 m A 2015 Pearson Educ Probs. 2-96/97 2-98. The force F has a magnitude of 80 lb and acts at the midpoint C of the thin rod. Express the force as a Cartesian vector. Prob. 2-99 Z *2-100.
