If 20 kg

a) Free body diagrams of blocks A and B separately

Draw.

b) the owner of block D for the action of block B

Calculate the minimum weight that should be.

c) Pulling force on the rope connecting block A to the wall

Find.


Static coefficient of friction between A block and C floor μAC = 0.4, static friction coefficient between A block and B block

μBA = 0.6. The friction between the rope connecting the D block to the B block and the pulley is neglected.
