Virtual Work for a System of Connected Rigid Bodies

Virtual Work for a System of Connected Rigid Bodies

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.

Composite Bodies

Composite Bodies

A composite body is a body made up of multiple parts, connected to form a larger, unified object. Each part has its own weight and center of gravity, which must be considered to determine the center of gravity of the composite body. In cases where the density or specific weight is constant, the center of gravity coincides with the centroid.
Composite bodies have widespread applications in mechanical engineering, from automobiles to aircraft to rockets. For example, an automobile wheel comprises...

Virtual Work

Virtual Work

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...

Planar Rigid-Body Motion

Planar Rigid-Body Motion

Understanding the movement of a rigid body in planar motion involves recognizing that every particle within this body is traversing a path that maintains a consistent distance from a specific plane. This concept is fundamental in the study of physics and mechanical engineering, and it allows us to comprehend better how objects move in space.
Planar motion is typically divided into three distinct categories. The first is rectilinear translation, demonstrated by a subway train that moves along...

Body Planes

Body Planes

Body planes in anatomy are imaginary flat surfaces used as reference points to divide the body into sections for anatomical study. These planes are essential for understanding the orientation, relationships, and spatial organization of anatomical structures.
The sagittal plane is the plane that divides the body or an organ vertically into right and left sides. If this vertical plane runs directly down the middle of the body resulting in equal division, it is called the midsagittal or median...

Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Summary

This summary is machine-generated.

Virtual object embodiment fades quickly after active control ceases. Disembodiment occurs nearly twice as fast as embodiment, highlighting the need for continuous sensorimotor experience in virtual reality applications.

Background:

Virtual object interactions are common in teleoperation, rehabilitation, and design.
Objects are rapidly integrated into the user's body schema (embodiment).
Understanding embodiment and disembodiment dynamics is crucial for applied settings.

Purpose of the Study:

To investigate the flexibility of disembodiment for virtual objects no longer actively controlled.
To explore how the timescale of disembodiment can be modified.

Main Methods:

Four web-based experiments were conducted.
Participants embodied a virtual hand via mouse/touchpad control.
Embodiment ratings were collected continuously during active use and after cessation of control.

Main Results:

Embodiment increased with active use and decreased after stopping.
Disembodiment occurred nearly twice as fast as embodiment, exhibiting a curved decay.
Anticipation of future control did not affect disembodiment dynamics.

Conclusions:

Continuous active control is essential for stable virtual object embodiment.
Virtual disembodiment applications rely on updated sensorimotor experiences.
After-effects of embodiment are unlikely to impact performance when switching virtual objects.
