The massless, 2-ft-wide gate shown in the figure below pivots about the frictionless hinge O. It is held in place by the 1950 lb counterweight, W. Determine the water depth, h.
2) A thin 4-ft-wide, right-angle
gate with negligible mass is free to pivot about a frictionless
hinge at point O. The horizontal portion of the gate covers a
1-ft-diameter drainpipe which contains air at atmospheric pressure.
Determine the minimum water depth h at which the gate will pivot to
allow water to flow through the pipe.
Ans: h = 1.88 ft
A homogeneous, 4-ft-wide, 14-ft-long rectangular gate weighing 800 lb is held in place by a horizontal flexible cable as shown in the figure below. Water acts against the gate, which is hinged at point A. Friction in the hinge is negligible. Determine the tension in the cable. 30 Keo Cable Water Gate 9.3ft14ft Hinge 1658.04 lb the tolerance is +/-2%
A rectangular gate having a width of 4 ft is located in the sloping side of a tank as shown in the figure below. The gate is hinged along its top edge and is held in position by the force P. Friction at the hinge and the weight of the gate can be neglected. Determine the required value of P. Water 29 ft Hinge Gate 60° lb
