hi guys.
got another question for ya.
.......
seems to of uploaded small but i explain.
a reservoir is designed to retain water to a max depth of 10metres. if the water level exceeds 10 metres, then a hinged semi circle gate will open to release any excess water. the gate has a radius of 1m. the gate is hinged 9 metres below the free surface.
what would be the force required to open gate?
what is the depth from the free surface to the the centre of pressure.
.......
i know the second moment of area of a semi circular surface is 0.1102R4
but not sure how to complete the question. help with working out the answer would be much appraicated so i can work back on the answer and see how to get it.
thanks
