Gate and strut
Problem statement
Gate ABD holds back all the water flowing through the area. The gate weighs 18 kN, uniformly distributed along its length, and is 2.4 m wide. The gate is pinned at A and is also supported by a strut at B. Taking the specific weight of water as 1000 kgf/m³, determine the reactions at support A and the axial force carried by the strut.
Figure data: AB = 1.6 m, BD = 1.8 m, strut BC = 1.6 m; the gate and the strut form 60° with the ground.
Concepts: hydrostatic pressure, pinned gate, axial force, reactions, specific weight of water
