For this gate, = 45, y 1 = 3 ft, and y 2 = 6 ft. Will the gate fall or stay in position

For this gate, α = 45°, y₁ = 3 ft, and y₂ = 6 ft. Will the gate fall or stay in position under the action of the hydrostatic and gravity forces if the gate itself weighs 18,000 lb and is 3ft wide? Assume T = 50°F. Use calculations to justify your answer.
