Question 1.
What is the definition of buoyant force?
Show hintHide hint
Consider what happens to objects in water.
Question 2.
What formula do we use to calculate the resultant force on a gate?
Show hintHide hint
What variables are involved in pressure?
3Question 3.
What is the resultant force needed to open a hydraulic gate?
- Pressure multiplied by area
- Only the weight of the gate
- Pressure at the bottom only
Show hintHide hint
Think about fluid properties.
4Question 4.

- True
- False
Show hintHide hint
Remember the principle of flotation.
Question 5.
A rectangular pool has dimensions 10m x 5m x 1m filled with water. Calculate the force exerted by the water on the bottom of the pool and the depth of water.
Show hintHide hint
Consider how pressure increases with depth.
Question 6.
An elliptical gate is submerged in water at a depth of 4m with a semi-major axis of 2m and semi-minor axis of 1m. Calculate the resultant force acting on the gate.
