Hydrostatic Pressure and Overturning Moment Assess C

What is density

• Density is the speed of an object
• Density is the weight of an object
• How much an object is packed

• Density is the force exerted by an object

Hydrostatic pressure is the pressure exerted by a fluid when it is:

• Still

• Moving

• Pressurized

• Evaporating

What happens to the Hydro static Pressure as you go deep down the water?

• Hydrostatic pressure increases
• Hydrostatic pressure becomes negative
• Hydrostatic pressure remains constant
• Hydrostatic pressure decreases

What is the center of gravity of an object?

• The center of gravity is only relevant for objects in motion
• The center of gravity is the point where the object is heaviest
• The center of gravity of an object is the point where the entire weight of the object can be considered to act.
• The center of gravity is always located at the top of the object

Which term describes the point where all the pressure forces acting on an object can be considered to act as a single force?

• Force nexus
• Pressure junction
• Stress convergence
• Center of pressure

Where is the center of pressure typically located on a submerged object?

• At the highest point of the submerged object
• At the center of mass of the object
• At the centroid of the submerged area of the object.
• At the lowest point of the submerged object

What is the significance of understanding the center of gravity and center of pressure in engineering?

• It is important for designing stable and balanced structures, vehicles, and aircraft, and for predicting their behavior under different conditions.
• It is only relevant for theoretical purposes
• It only applies to small-scale projects
• It has no significance in engineering

In the context of a dam, what could cause an overturning moment?

• Uniform pressure distribution on the dam surface

• Earthquake shaking the foundation of the dam
• Equal distribution of hydrostatic pressure along the height of the dam

• The resultant force not passing through the center of gravity of the dam
