Old MacDonald had a farm, e i , e i , oh ! And on that farm he had a gate, e i , e i , oh ! And a squeak, squeak, here. A squeak, squeak, there. And a squeak, squeak, everywhere . . . The gate is ℓ = 3 m wide and h = 2.47 m tall with hinges attached to the top and bot- tom. The guide wire makes an angle of α = 39 ◦ with the top of the gate and has a tension of 221 N. The mass of the gate is 30.9 kg. Determine the magnitude of the horizon- tal force exerted on the gate by the bottom hinge. The acceleration of gravity is 9.8 m/s2 . Answer in units of N. Okay the reason why I am having problems with this is because well im just not sure I know where to start. I think I am just missing something obvious, and my book does not have a whole lot to say about this type of problem. Any Help?
