Bitz & Bob is a children's animated television series that originally aired on CBeebies. [1] The series focuses on the adventures of a sister and brother, who explore various concepts related to STEAM (Science, Technology, Engineering, Arts, and Mathematics) through imaginative play and problem-solving.
The bearings that form the fulcrum of a lever and that allow the wheel and axle and pulleys to rotate are examples of a kinematic pair called a hinged joint. Similarly, the flat surface of an inclined plane and wedge are examples of the kinematic pair called a sliding joint. The screw is usually identified as its own kinematic pair called a ...
The types of mechanical energy used to power mechanical toys include rubber bands, springs, and flywheels.. Mechanical toys use 4 types of different movements, rotary (going around in a circle), linear (moving in a straight line then stopping), reciprocating (moving backwards and forwards continuously in a straight line) and oscillating (moving backwards and forwards in a curve).
The ratio of the output to the applied force is called the mechanical advantage. Simple machines can be regarded as the elementary "building blocks" of which all more complicated machines (sometimes called "compound machines" [6] [7]) are composed. [2] [8] For example, wheels, levers, and pulleys are all used in the mechanism of a bicycle.
In some engineering jargons, the two words have different meanings, in which engine is a device that burns or otherwise consumes fuel, changing its chemical composition, and a motor is a device driven by electricity, air, or hydraulic pressure, which does not change the chemical composition of its energy source.
Hamman Manus R mechanical computer, produced in Germany by the DeTeWe company between 1953 and 1959. A mechanical computer is a computer built from mechanical components such as levers and gears rather than electronic components. The most common examples are adding machines and mechanical counters, which use the turning of gears to increment ...
The lead determines the mechanical advantage of the screw; the smaller the lead, the higher the mechanical advantage. [20] The pitch is defined as the axial distance between the crests of adjacent threads. In most screws, called "single start" screws, which have a single helical thread wrapped around them, the lead and pitch are equal.
Various machine components used in mechanical engineering. Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [1]
