The rigid gate, OAB, in Figure is hinged at O and rests against a rigid support at B. What is the minimum horizontal force, P, is required to hold the gate closed if its width is 4 m? Neglect the weight of the gate and friction in the hinge The back of th
a) Determine the resultant force acting on the inclined circular gate. b) Find the location of center of pressure. c) Calculate the minimum weight of the block that can open the gate. (Assume that gate is weightless) (a=60 cm, γwater=9810 N/m3 )
At points A, B C and D calculate the absolute pressure. (Patm=96 kPa, γwater=9810 N/m3 )
