Hint:Egg beater is used for mixing the ingredients by continuously hitting and rotating. Mixers help automate the repetitive tasks of stirring, whisking or beating. Beaters are used to mix ingredients that are used in cooking.
Complete answer: The beaters continuously hit the ingredients that are to be mixed and for performing this task beaters have to rotate. Egg beater is an example of wheel and axle machine as it is used to mix ingredients by simply rotating with help of wheel and axle setup.
There are six simple machines: -Wheel and axle -The lever -The inclined plane -The pulley -The screw -The wedge The wheel and axle consist of a disk, known as wheel, with a rod through the centre of it, known as axle. This type of system works on the principle of angular momentum and torque to do work on objects.
When wheels are attached to an axle it can turn itself freely about the axle. Due to this the wheels are in motion. In a mixer the beater has to rotate about a specific axis and mix the ingredients. For this wheel and axle combination is used. The axle is supported by a bearing which allows rotation.
A small force which is applied from the wheel can amplify large rods attached to the axle. A force applied to the outer rim of a wheel creates greater torque on the axle than the same force applied to an axle without a wheel. The larger the wheel, the larger is the mechanical advantage, and easier it is to turn the axle.Hence, an egg beater is an wheel-axle arrangement.
Note:Pulley is also used for rotating and lifting purpose but pulley cannot provide complete rotation about the axis. Different devices such as fans also use the same concept of wheel and axle. Also, keep in mind that the axis of rotation remains the same.
