PROBLEM 3.39 Consider the volleyball net shown. Determine the angle formed by guy wires AD and AC. SOLUTION First note and By definition or or AB = ~(-6.5)' + (-S)' + (2)' = 10.5 ft AC = ~(O)' + (-S)' + (6)' = 10 ft AB = -{6.5 ft)I-(S ft)J + (2 ft)k AC = -{S ft)j + (6 ft)k AB· AC =(AB)(AC)co,O (--6.51 - Sj + 2k)· (-Sj+ 6k) = (l0.5)(l0)co,O (--6.5)(0) + (-S)(-S) + (2X6) = 105 co,O eos8==O.7238) or 8=43.6 0 ...

O.3m , PROBLEM 3.48 The O.61x1.00-m lid ABeD of a storage bin is hinged along side AB and is held open by looping cord DEC over a frictimdess hook at E. If the reMioD in the cord is 66 N, determine the moment about each of the coordinate axes of the force exerted by the cord at C. SOLUTION First note z ~ .j(0.61)' - (0.11)' = 0.60 m Then deE = J( -0.7)' + (0.6)' + (-0.6)' = 1.1 m and TeE ~ 66 N (-<l.7i+ 0.6J-0.6k) l.l = 6[-(7 N)i +(6 N)j-(6
