It is an engine.A steam turbine is a heat engine that uses the expansion of steam passing through stationary nozzles and blades on a shaft to turn the shaft. The steam can move through the turbine axially (one end of shaft to the other end), radially (shaft to outer casing), or tangentially (around the outer edges of the turbine wheel). In an impulse turbine, the steam is expanded in nozzles and pushes the blades. In a reaction turbine the steam is expanded in the nozzles AND in the blades, the reaction of the expansion of the steam pushes away from the blades spinning the wheel in the process. The expansion of the steam is necessary to increase its velocity through the turbine.
Levers (the two blades) and wedges (the blade edges).
Scissors are primarily composed of two first-class levers. Each blade acts as a lever, with the pivot point (fulcrum) located at the screw that holds the two blades together. When the handles are squeezed, the levers move the blades together to cut through material. Additionally, the blades can also be considered as wedges, as their sharp edges help in cutting.
Cutting cloth with scissors that have dull blades is challenging because the blades can't create a clean, sharp edge, leading to fraying and uneven cuts. Dull blades require more force to cut through the fabric, which can result in jagged edges and may damage the material. Additionally, the lack of precision can make it difficult to achieve the desired shape or size. To ensure clean and efficient cutting, it's essential to use sharp scissors.
Scissors are a combination of two simple machines: levers and wedges. The two blades act as levers that pivot around a central fulcrum, allowing for a mechanical advantage when cutting. The sharp edges of the blades function as wedges, converging to slice through materials. Together, these simple machines enhance the efficiency and effectiveness of the cutting action.

That is a fairly broad question. Having worked on aircraft for many years I have seen many areas that are " susceptible to damage" . I have seen considerable damages on ALL the following, in order. - Wingtips, wing leading and trailing edges, engine nacelles, propeller blades, undercarriage, turbine blades at front of engine, tail surfaces, nosecones.
To sharpen hedge trimmer blades, you can use a grinder to grind down the edges. You can also purchase sharpening tools.
23 edges because a rectangle has 5 edges and 6 vertices, 5 times 6 is 30 subtracted by the number of faces(7) is 23.
Clipper blades should be stored in a cool, dry place to prevent rust and damage. It's best to keep them in a dedicated blade case or holder that protects the cutting edges from nicks and dust. Additionally, ensure they are cleaned and oiled before storage to maintain their sharpness and longevity. Avoid stacking blades directly on top of each other to prevent accidental dulling.
The hairy, coarse blades have sharp edges that help keep predators from eating the plant. Since these sharp edges help protect it from predators many birds use them for nesting.
Of course you should. Sharpen in the same manner as any blade making sure it is balanced when finished. Make note that some mulching blades have 2 cutting edges. Sharpen those using the same method.

It helps attack. A shark's tooth has tiny blades on its edges. When a shark shakes it's head while attacking, the blades help rip apart it's prey.
Yes, the saw-edges on the blades are irritating to their throats and stomachs and can cause vomiting. If your dog is eating grass and looking miserable, you should take it to the vet to find the cause of the stomach upset.
