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 total moment about A is  :  ( a. 399.80 ,  b. 763.25 ,  c.302.88, d.66.63 ,  e. 793.53 )

2- Z-component of total moment about B is : ( a. 29.25 ,  b. 348.38 ,  c. 175.52 , d.132.97 , e. 335.08 )

3- X-component of total moment about B is: (a. 755.36 , b.726.53 , c.380.56 , d.288.31  , e. 63.43 )
