cân đĩa

The Vietnamese word "cân đĩa" refers to a type of scale known in English as a "roberval balance" or simply a "balance scale." This is a device used to measure the weight of an object by comparing it to known weights.

Explanation:

• Basic Meaning: "Cân đĩa" is a weighing instrument that typically consists of a beam balanced on a fulcrum. It has two pans or plates (the "đĩa") where the object to be weighed is placed on one side, and weights are added to the other side until equilibrium is achieved.

Usage Instructions:

• "Cân đĩa" is commonly used in science laboratories, classrooms, and sometimes in kitchens for precise measurements.
• When using "cân đĩa," you place the item you want to weigh on one side and adjust the weights on the other side until the beam is level, indicating that the weights are equal.

Example:

• Basic Example: "Tôi sử dụng cân đĩa để đo khối lượng của chất rắn." (I use the balance scale to measure the mass of a solid substance.)

Advanced Usage:

• "Cân đĩa" can also be used metaphorically in discussions about balance in life or balancing different aspects of a situation, indicating the need for equilibrium in various contexts.

Word Variants:

• There are no direct variants of "cân đĩa," but you might encounter related terms like "cân điện tử" (digital scale) which is another type of weighing device that uses electronic sensors instead of a balance mechanism.

Different Meanings:

• While "cân đĩa" primarily refers to the balance scale, in certain contexts, it could refer to the concept of weighing decisions or options, emphasizing the need for careful consideration.

Synonyms:

• "Cân" (scale) is a more general term that can refer to any weighing device.
