COSMOS: Complete Online Solutions Manual Organization System Chapter 3, Solution 55. Have ( M AD = λ AD ⋅ rE/ A × FEF where λ AD ) JJJG AD = AD λ AD = ( 7.2 m ) i + ( 0.9 m ) j ( 7.2 m )2 + ( 0.9 m )2 = 0.99228 i + 0.124035 j rE/ A = ( 2.1 m ) i − ( 0.9 m ) j FEF = FEF JJJG ( 0.3 m ) i + (1.2 m ) j + ( 2.4 m ) k  EF = ( 24.3 kN )  EF ( 0.3 m )2 + (1.2 m )2 + ( 2.4 m )2 = ( 2.7 kN ) i + (10.8 kN ) j + ( 21.6 kN ) k Then M AD 0.99228 0.124035 0 = 2.1 − 0.9 0 kN ⋅ m 2.7 10.8 21.6 = −19.2899 − 5.6262 = − 24.916 kN ⋅ m or M AD = − 24.9 kN ⋅ m .
