Suppose pistons A (diameter 1.25 inches) and B (diameter 0.75 inches) are connected by a simple hydraulic system. How much force does B exert if the input force on A is 3 pounds?
What will be an ideal response?
Find the pressure that exists within piston A:
Pressure = input force x area of piston A
= 3 pounds x 1.22 square inches
Pressure = 3.66 psi
Find force that piston B exerts:
Force = pressure x area of piston
= 3.66 psi x 0.44 square inches
Force =1.61 pounds

What will be an ideal response?
To improve humidity control for air-conditioning systems installed in humid climates, the air-conditioning system selected should:
A) Be sized larger than normal, have a high sensible capacity, and higher-than-normal airflow. B) Have a high sensible cooling capacity and higher-than-normal airflow. C) Be sized somewhat larger than the load study indicates to allow for extra latent cooling. D) Have a high latent cooling capacity and not be oversized.
