An air cylinder has a 2-inch bore and a 1-inch rod. Air is available at 100 psig. What is the maximum extension and retraction force available from the cylinder?

A. 100 lb, 100 lb
B. 314 lb, 235 lb
C. 314 lb, 200 lb
D. 200 lb, 78 lb

Answer :

Final answer:

An air cylinder's maximum extension and retraction forces can be calculated using pressure and piston area. The correct answer is option c: 314lb, 200lb.

Explanation:

The maximum extension and retraction force available from the air cylinder can be determined using the formula:

F = P * A

Where F is the force, P is the pressure, and A is the area of the piston. Given the bore and rod measurements along with the air pressure, you can calculate the maximum forces for extension and retraction.

The correct answer is option c. 314lb, 200lb.
