EXAM STUDY MATERIALS July 26, 2024 9:30 AM Pneumatic Exam Questions With Verified Answers. An object's inertia determines how much force is needed to lift or move the ob ject or to change its speed or direction of movement. - answer✔✔True Most pressure gauges in a pneumatic system measure only pressure that is higher than the atmospheric pressure surrounding them. - answer✔✔True In a pneumatic system, mechanical energy is produced by the motor. - answer✔✔False Pascal's Law states that when a gas is confined under pressure in a closed container, the pressure is equally transmitted in all directions by the gas - answer✔✔True If the volume of a confined quantity of gas remains the same, the change in the pressure of the gas varies directly with a change in the absolute temperature(T) of the gas. If the temperature increases, then the pressure of the confined gas increases. - answer✔✔True In a pneumatic system, the force that pe rmits a small amount of pressure to move a larger object is called pneumatic leverage or force multiplication. - answer✔✔True Bernoulli's Law states that, in an ideal system, if air velocity increases, the kinetic energy of the air also increases, while th e total energy of air does not remain constant. - answer✔✔False A pneumatic system is quite different from a hydraulic system. It differs not only in the components it contains, but also in the flow paths through the system. - answer✔✔True The three types of symbols used in drawing pneumatic circuit diagrams are pictorial, cutaway, and schematic. - answer✔✔True In a pneumatic timing circuit, the timing is a function of the size of the restriction and the volume of the reservoir, however, the magnitude(press ureO of the air signal also affetcs timing. - answer✔✔True Industrial technicians usually designs symbols for special pneumatic devices. - answer✔✔False To understand the operation of many special pneumatic devices, obtain the manufacturer's service bullet ins, which describe their operation. - answer✔✔True A system that uses a gas for transmitting force is called - answer✔✔pneumatic system EXAM STUDY MATERIALS July 26, 2024 9:30 AM A force is a push or a pull exerted on an object to change its position or movement and in a pneumatic system this forc e is exerted by - answer✔✔compressed air In a pneumatic system, the force in pounds is exerted by air pressure acting on the area of a moving piston in a cylinder. What equation is used to determine the amount of work done by a cylinder? - answer✔✔force x piston travel The amount of work done by a cylinder that exerts a force of 120 in -lb and a 10 -in. stroke is - answer✔✔100 ft -lbs In a pneumatic system, Power is defined as the amount of work(foot -pounds) done in a given length of time(seconds or minutes), or foot -pounds per minute. What equation is used to determine the amount of power? - answer✔✔work/time can be described as the r apid intermingling of the molecules of one gas with another. - answer✔✔diffusion is the ideal type of airflow in a pneumatic system because the air layers move in nearly parallel lines. - answer✔✔streamline The _________ of air is its resistance to flow, b ecause it is a measure of the air's internal friction. - answer✔✔viscosity _______ symbols or views are useful for showing the physical relationship and internconnections between pneumatic components and benefit the installer by clearly showing the connect ions between pneumatic components. - answer✔✔pictorial _______ symbols emphasize the construction of pneumatic components and are of more benefit in troubleshooting pneumatic components because they show the internal arrangement of the parts. - answer✔✔cutaway _______ symbols more clearly emphasize the function and method of operation of pneumatic components and are the most widely used kind of symbol - answer✔✔schematic _______ are used to represent pneumatic rotary motion or devices such as compressors an d motors. - answer✔✔circles _________ symbols are an organized combination of complete and simplified symbols. - answer✔✔composite Pneumatic main line conductors are called working lines and are drawn as a __________. - answer✔✔single unbroken line Pneumat ic pilot or signal line conductors are drawn as a __________. - answer✔✔series of long dashes
