Question
The 0.39*0.81-m lid ABCD of a storage bin is hinged along side
AB and is held open by two cords ED and EC. The tension in ED is 400.14 N and in EC is 430.92} N.
1 -y-component of tension ED is : (a. -121.89 , b. -241.93 , c. -20.31 , d. -232.70, e. -92.34 )
2- X-component of the resultant is : (a. 192.07 , b. 78.80 , c. 398.91 , d. 246.24 , e. 374.28 )
3- X-component of total moment about A is : ( a. -313.03 , b. -507.11 , c. -244.17 , d. -100.17 , e. -475.81 )
