A lot of students sometimes find that it seems difficult to work out the areas of the irregular figures. Actually, all the difficult maths problems can be solved. The most important thing depends on how students have mastered the knowledge of maths learned and how students are to use those ...

One of the most primitive types of gears we could look at would be a wheel with wooden pegs sticking out of it. The problem with this type of gear is that the distance from the center of each gear to the point of contact changes as the gears rotate. This means that the gear ratio ...
Understanding the concept of the gear ratio is easy if you understand the concept of the circumference of a circle. Keep in mind that the circumference of a circle is equal to the diameter of the circle multiplied by pi (pi is equal to 3.14159...). Therefore, if you have a circle or...

That depends on the size of the cylinder, which, in turn, depends on two key measurements: the diameter of the cylinder (called its bore) and how far the piston moves out (its stroke). The area of a circle is π× radius2, and since the bore is twice the radius, the useful ...
A work of art can be defined as a section of space (visual, auditory, tactile, etc.) that has been assigned a particular status. It is not our intention to define this status—philosophical aesthetics has been addressing this issue for centuries. Rather, we aim to pinpoint the mechanisms ...
