2024年4月28日 · However, some sources say that they shouldn't be equal because they are defined differently and that thermodynamic work is work done by a thermodynamic process (that can cause a mechanical work), while mechanical work is the work done by a force. I don't really understand this.

2022年3月26日 · What is the difference between thermodynamic and mechanical work? Should they show equal values in an experiment? If yes, what possible errors could cause if there is a difference in their values?

2011年6月7日 · Because it doesn't have a physical meaning. if a body moves over a distance, the work done by the force is defined as the force component in the direction of the motion times the distance traveled: For a differential distance, the differential work is the dot product of the force vector times the displacement vector: and by integrating over the trajectory of the motion you …

2007年9月26日 · Can you explain why mechanical work is defined as W=Fx? Where x is the displacement of the point of exertion of the force toward the direction of the force. Waiting for yr response. Thx.

2006年2月2日 · Hi, I am wondering how I can reconcile the concept of work as it is introduced in mechanics with the way work is defined in thermodynamics, as a transfer of energy. I would also like to maintain the convention that negative work means a …

2021年11月26日 · I want to understand how the weight machines work that we use in homes and shops. I have been working on force and motion chapter and I was curious how this weight machine actually push up and how it applies force to the feet of the person being weighed? What reading is this that we see in...

2011年3月28日 · The work environment for mechanical engineers can be physically demanding, depending on the nature of the project. They may need to spend long hours standing, walking, or working in confined spaces.

2014年1月29日 · FAQ: Understanding Mechanical Work: Ideal Gas and Fixed Pressure What is work done by an ideal gas? The work done by an ideal gas is the energy transferred to or from the gas due to a change in its volume. This change in volume can be caused by an external force or by the gas expanding or compressing on its own.

2019年1月20日 · Mechanical work, macroscopic work, work all refer to the same thing: measureable work due to pressure acting through a change in volume done by or on a thermodynamic system.

2005年5月1日 · In summary, the conversation discusses a physics problem involving a conducting rod in a magnetic field. The conversation covers calculating the magnitude and direction of induced emf, the force required to maintain the rod in motion, and comparing the rate of mechanical work done by force with the rate of heat development in the circuit. The main …
