That’s a wheel and axle! It’s a simple machine where a big wheel and a smaller axle work together to make tasks easier by reducing effort.
any where in the world a squire is a squire, like triangle , pentagon, etc all objects are same but they pronounce in different languages but come to the shape of the objective is represented by the same symbol.
Machines are inanimate. Machines do not eat, sleep, rest, breathe, and they do not have a heart beat. Machines are just objects, inanimate objects for the use of humans.
reflect light well-normally shinysmooth pale colour objects: mirror, glass, shiny metal, tin foil...these objects favour a good image due to the reflection of light is regular do not reflect light well-usually rough, matt , dark colured objects: tree trunk, car wheel, dark carboard, brick, stone, dark opaque plastic... These objects diffuse the picture or do not giva a picture at all because reflected light is irregular.

the wheel and axle is a simple machine made from two circular objects and are different sizes that are attached and rotate together and it is a lever that can rotate to 360 degrees
wheel and axel
Two circular objects of different sizes that rotate together is a wheel and axle. Inclined plane wrapped around a central cylinder or bar to form a spiral is a screw.
No, the law of acceleration does not apply to objects in circular motion. Instead, objects in circular motion follow the principles of centripetal acceleration and centripetal force, which keep the object moving in its circular path.
The circular orbit equation used to calculate the motion of objects in a circular path is called the centripetal force equation, which is F mv2/r.
If there are n objects and you have to choose r objects then the number of permutations is (n!)/((n-r)!). For circular permutations if you have n objects then the number of circular permutations is (n-1)!
Orbits sould be circular because the centripetal force that keeps objects in circular motion is constant (it is gravity!)
That's a good question. I have never thought about that. But yes, for anything excluding circular objects, length and width are used.
No, pliers are not a lever. Pliers are a type of hand tool used for gripping, twisting, or cutting objects, while a lever is a simple machine consisting of a rigid bar that pivots around a fixed point to help in lifting or moving heavy objects.
Examples of circular objects include a wheel, which is a perfect circle used in vehicles; a clock face, which displays time in a circular format; and a dinner plate, typically round for serving food. Other examples are coins, which are often circular and used as currency, and hula hoops, which are circular toys used for exercise and fun. Each of these objects demonstrates the versatility and functionality of circular shapes in everyday life.
