49050N - - - To Calculate value ofh. Guen: sm x2m Rectangular plate Fust we will find out the Force Facting on the plate From3 . Total Force F is givenby = fgan = 1000x9.81 xuh - 19620 h N The Centre os pressure of the immersed surface ha h* = In Sin
Now in the ACHD - CH= * = 2h LCPH=60° CHE = Since 2 . AC=AD-CD = 25-4h = 20 m Taking Moment about hinge, weget 490 SO X 5 = F
