HW18: FBD of the bucket and whole upper assembly
up to EF to find force in EF and reactions at H. Then
draw a FBD of CDEH to find force in AD. AD can
also be found from the FBD of the entire upper crane
up to CD. Draw a FBD of the bucket to find the force
at K and J. The shovel load acting at G is 1.25Mg.
Answer: FEF=8.18kN, FAD=158 kN
