Question: The friction coefficient between the blocks and horizontal - vertical planes in the figure is 0 . 3 . It is known that the weight

The friction coefficient between the blocks and horizontal-vertical planes in the figure is 0.3. It is known that the weight of block A is 120 N. Wedge C, whose weight is negligible, is wanted to be pushed under block A. Find the smallest value of the force P required to start the movement.
