Virtual Work01:20

Virtual Work

982
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Virtual Work for a System of Connected Rigid Bodies

490
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.

Principle of Virtual Work: Problem Solving

1.3K
The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.
To apply the principle of virtual work,...

Summary
This summary is machine-generated.

Work from Home (WFH) is feasible post-pandemic, with work dependence, environment, and work-life balance influencing future WFH willingness. Job performance, social interaction, and supervisor roles did not significantly impact this decision.

Area of Science:

  • Organizational Behavior
  • Human Resource Management
  • Pandemic Studies

Background:

  • The COVID-19 pandemic necessitated widespread adoption of Work from Home (WFH).
  • Existing research on WFH antecedents predates the pandemic context.
  • A gap exists in understanding WFH feasibility and influencing factors during a global health crisis.

Purpose of the Study:

  • To investigate the future possibility of Work from Home (WFH) post-pandemic.
  • To identify key antecedents influencing employees' willingness to continue WFH.
  • To bridge the gap between pre-pandemic WFH research and the current pandemic situation.

Main Methods:

  • A structured questionnaire with 19 items, including 6 on home work infrastructure, was used.
  • Data collected from 138 full-time employees working remotely in India.
  • Quantitative and qualitative analyses were employed to assess hypotheses.

Main Results:

  • Work dependence, work environment, and work-life balance were found to significantly influence the willingness for future WFH.
  • Hypotheses regarding the direct impact of job performance, social interaction, and supervisor's role were refuted.
  • The study identified specific factors that encourage or discourage future WFH adoption.

Conclusions:

  • Work-life balance, dependence, and environment are critical for sustained WFH.
  • Job performance, social interaction, and supervisor roles require further investigation in the WFH context.
  • Findings offer practical insights for organizations designing future remote work policies.
