What is the maximum working force that may be acting on an air operated actuator with a surface area of 60 square inches and a 30psig air supply?

To determine the maximum working force acting on an air-operated actuator, we can use the formula that relates pressure, area, and force. The formula can be expressed as:

Force (lbs) = Pressure (psi) x Area (sq in)

In this scenario, the surface area of the actuator is 60 square inches, and the supplied air pressure is 30 psi. By substituting the given values into the formula, we can calculate the force:

Force = 30 psi x 60 sq in = 1,800 lbs

This calculation shows that the actuator can exert a maximum working force of 1,800 pounds under the specified conditions. Therefore, the answer is indeed the maximum working force that can be generated by the actuator with the specified air supply and surface area, making it the correct choice.
