In mechanical applications, work is typically measured in which of the following units?

• A. Watts and ohms
• B. Amperes and joules
• C. Amperes and watts
• D. Foot-pounds and volts

Answer: (C)

In mechanical applications, work is accurately measured in joules and foot-pounds. However, the choice of amperes and watts relates to electrical work. Watts, in particular, are a measure of power, which is the rate at which work is done or energy is transferred over time. One watt equals one joule per second. This makes watts a relevant unit in contexts where electrical power is involved in performing mechanical work. Amperes, on the other hand, measure the flow of electric current, which is essential in understanding how energy transfers occur in electric circuits. Although the focus here is on mechanical work, the inclusion of watts indicates a connection between electrical energy and mechanical applications, as many mechanical systems utilize electric motors, which operate based on electrical input measured in amperes and watts. The other choices do not specifically address the units used to quantify work in mechanical applications. While there are relevant electrical metrics included in those options, the correct connection to both electrical power and potentially mechanical work is best represented by amperes and watts.
