For the gate shown, = 45, y 1 = 1 m, and y 2 = 4

For the gate shown, α = 45°, y₁ = 1 m, and y₂ = 4 m. Will the gate fall or stay in position under the action of the hydrostatic and gravity forces if the gate itself weighs 150 kN and is 1.0 m wide? Assume T = 10°C. Use calculations to justify your answer.
