Determine the force P necessary to lift the shield A, covering a rectangular hole with a height of h = 4m and a width of b = 6m. The water pressure in front of the shield N = 7.5m; coefficient of friction in the guides of the shield when lifting f = 0.02; shield weight 1t. What electric motor needs to be installed to fully lift the shield in t = 120s if the transmission efficiency is 0.70? (Atmospheric pressure on the surface of the water and behind the shield).
Given: h = 4m; b = 6m; H = 7.5m; f = 0.02; m = 1t = 1000kg; t = 120s; η = 0.70
