Yeah I've just added it to my original and free body diagram. At which point would i cslculate the moment?

There are no details on the latch so yes your assumptions are valid a simple latch. There will be a reaction force preventing rotation in the zy plane and act perpendicularly to the door. Is this correct

Well the hinges are the only thing supporting the gate so yes they take the load. The hinges also resist any rotation, however as the hinges are not evenly or symmetrically spaced on the door there must be a rotational force in the system that is resisted by the hinges that i am not accounting for

Those dimensions are to the center of the hinge

The three hinges are dimensioned from the bottom of the door. The bottom hinge is 0.375m from the bottom of the door the middle hinge is 1.975m and the top hinge is 3.375m from the bottom of the door

Yes it is assumed to be fixed ie closed and locked

how can I upload an image of the free body diagram

Homework Statement Determine the forces at the 3 hinges of closed gate with a wind pressure of 700Pa on the gate. Mass of gate = 236kg wind pressure = 700Pa (apllied perpendicularly to the gate) gate dimensions: 4.1m high, 2.45m wide Distacnce from bottom of door to centre of hinges...
