What is a steam turbine?
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.
What are the two simple machines in pair of scissors?
Levers (the two blades) and wedges (the blade edges).
What all simple machine in 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.
How many faces edges vertices does a dodecahedron have?

When prim algorithm fail?

What are five areas on an aircraft that are susceptible to damage?
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.
How do you sharpen hedge trimmer blades?
To sharpen hedge trimmer blades, you can use a grinder to grind down the edges. You can also purchase sharpening tools.
How many strait edges does a rectangular prism have?
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.
What is the grass adapting?
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.
Should you sharpen a lawnmower muching blade?
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.
What is elephant grasses adaptions?
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.
What does a great white's teeth do for a great white?
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.
Do dogs eat grass to throw up?
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.

scissors with zigzag edges on them. they are in the scissor isle.
