Question

: Which of the following statement is not correct about pneumatic actuators? Pneumatics actuators operation is based on the concept of pressure as force per unit area Pneumatics actuators use compressed air to generate motion Pneumatics actuators generate only rotary motion Pneumatics actuators mainly comprises of a piston, a cylinder, and valve

Answer 1

Pneumatic actuators can generate either linear or rotary motion, depending on their design and application.

Step-by-step explanation:

Pneumatic actuators are devices that use compressed air to generate motion. They work based on the concept of pressure as force per unit area. However, the statement 'Pneumatic actuators generate only rotary motion' is not correct. Pneumatic actuators can generate both linear and rotary motion depending on their design and application.

Example: A pneumatic actuator with a piston and cylinder can generate linear motion. When compressed air is supplied to the cylinder, it pushes the piston in one direction creating linear motion.
