Which measurement is used for power in machinery?

• A. Ohms
• B. Feet per second
• C. FT*LBS/S or Watts
• D. Newtons

Answer: (C)

Power in machinery is measured in terms of the rate at which work is done or the rate at which energy is transferred or converted. The correct measurement for power is expressed in units such as watts or foot-pounds per second (FT*LBS/S). Watts, being the standard unit of power in the International System of Units (SI), quantifies how much energy is used per unit of time. Specifically, one watt is defined as one joule per second. In various applications, particularly in mechanic and electrical contexts, understanding power in these terms is crucial for efficiency and performance evaluation. Foot-pounds per second is another expression of power that indicates the amount of energy (foot-pounds) being exerted or converted per second. This concept aligns directly with practical uses in machinery, where power output may dictate the operation of tools or engines by helping determine capabilities and performance criteria. In contrast, ohms measure electrical resistance; feet per second quantify speed; and newtons represent force. Each of these units serves a different purpose and does not pertain to the measurement of power, further solidifying why the correct answer specifically relates to power measurement in machinery.
