Question

If the master cylinder in a hydraulic system is at a greater height than the cylinder it is controlling, how will this affect the force produced at the controlled cylinder?

a) Force remains constant
b) Force increases
c) Force decreases
d) No effect on force

Answer 1

When the master cylinder in a hydraulic system is at a greater height than the cylinder it is controlling, the force produced at the controlled cylinder decreases.

Step-by-step explanation:

In a hydraulic system, when the master cylinder is at a greater height than the cylinder it is controlling, the force produced at the controlled cylinder decreases. This is because the pressure is directly proportional to the height of the liquid column. As the height of the liquid column decreases, the pressure decreases, resulting in a decrease in force at the controlled cylinder.

For example, let's say the master cylinder has a smaller diameter than the controlled cylinder. When the master cylinder is at a greater height, the pressure at the controlled cylinder will be less than the pressure at the master cylinder. As a result, the force produced at the controlled cylinder will be less than the force applied at the master cylinder.
