Flexible hose under pressure in a hydraulic system will __________.

Question 1 of 27070

Flexible hose under pressure in a hydraulic system will __________.

🔍 Key Concepts

• Pascal's Law and how pressure acts in a confined fluid • How flexible hose walls deform under internal pressure • Difference between changes in length vs diameter when stretched or pressurized

💭 Think About

• When you pressurize a flexible hose, which direction is the material being pushed—outward, along its length, or sideways? • Think about a garden hose when water is turned on at high pressure: what happens to its thickness and its length? • If the wall of the hose is being stretched by internal pressure, how would that affect its circumference and its overall length?

✅ Before You Answer

• Visualize a round balloon being inflated: what happens to diameter and length, and apply that idea to a hose. • Ignore any answer that talks about motion not directly caused by internal pressure in all directions (like twisting for no reason). • Focus on options that describe realistic material deformation under uniform internal pressure, not a change in direction of the fluid.
