A clamp or vice that uses pneumatic power to close and hold pressure upon a part. Pneumatic means air. In this context compressed air.

All pneumatic systems start with an aircompressor. This compressor is usually rigged with a electronic pressure switch, which shuts the compressor off once the system has reached pressure. The compressor uses an accumulator to store additional compressed air in reserve in case the amount of air required by the system exceeds the compressor's output. Both of these components are connected to an air regulator, which reduces the combined compressor and accumulator output pressure to the desired psi (usually pressure gauges are placed before and after the regulator). This resulting air feed is then connected to a series of mechanical or electric solenoids (air valves). Two lines run out of each solenoid, each connects to an opposite side of the pneumatic piston (s) that the solenoid controls. When triggered, the solenoids direct the air into the front or back of the piston depending on the desired direction of the piston. Return air from the opposite side of the piston is usually vented. This results in the pneumatic pistons emitting a hissing sound whenever they are moved.
Example: A bicycle tire pump uses mechanical energy (your body) and converts it into pneumatic energy (air out of the hose).
human respiratory uses air pressure like pneumatic system does
Sand blasting uses air pressure as an ejector within the blasting process. This is how the pneumatic system is used in a pneumatic sand or paint blaster.
a jackhammer uses a pneumatic system.the jackhammer is a direct combination of a hammer and a chisel
Answer: Mechanical advantage can be achieved just by adding more loops or pulleys. It is given that to lift a crate, a pulley system exerts a force of 2,740 newtons. It is required to find the mechanical advantage of the pulley system if the input force is 250 newtons What is the mechanical advantage of the pulley system if the exerted force changes from 2,740 newtons to 250 newtons? As if the force does some work, it increases the distance. Mechanical advantage does nothing with the number of pulleys. It only depends on the weight that is to be lift. Also, F1/F2 = 2740/250 = 10.96 The multiple pulleys create mechanical advantage. It can be achieved just by adding more loops or pulleys. Therefore, Mechanical advantage can be achieved just by adding more loops or pulleys.
Neither. Pneumatic equipment uses air, under pressure, to convey mechanical energy from one place to the other. Hydraulic equipment uses water for the same reason. A hot-air balloon uses less dense hot air to fill it's balloon. Due to gravity the more dense cold air sinks down and pushes the hot air filled balloon up. The burner uses a mechanical arm with a spring (with a string and handle attached) to control the amount flame.
the main difference between hydraulic and pneumatic system is that hydraulics uses fluid to power their system and pneumatic uses air (in that case air is not a fluid) All matter is made up with all particles. thanks you can see more answer in this web i put these all answer.

The amount of force required to lift a weight is inversely proportional to the number of suspension lines. A multiple pulley system allows the load to be distributed across several lines and greatly reduces the amount of force required to lift the weight.. The load that takes mechanical power to lift with a single pulley can be lifted by a single person with a multiple pulley set-up

Pulley systems are used in the real world to lift large masses onto tall heights. You might have seen the workers repairing the roof of a house and using the pulley system to lift their tools or materials to the roof. A pulley is an example of a simple machine.The pulley system consists of one or more pulleys and a rope or a cable. The number of pulleys used may increase or decrease the mechanical advantage of the system. Generally, the higher the mechanical advantage is, the easier it is to lift the object that is being lifted.Overall, no matter how easy it is to use the pulley system, the system itself is not very efficient due to the force of friction. For example, one has to pull two meters of rope of cable through the pulleys in order to lift an object one meter.The applet below illustrates just that. Select the number of pulleys and drag the mouse to see the inefficiency of the system.
