Gate AB is immersed in oil (SG = 0.82) and hinged at point A. The hinge is blocked, so that the gate cannot be opened. Length AB and width of the gate are 1.2m and 0.8m respectively. Assume the weight of the gate is negligible. a. How great is the resultant force on the gate due to the pressure from the oil? b. How large is the moment acting on hinge A?
