Static Balance in Young Children

Child Development, 1984
CLARK, JANE E., and WATKINS, DEBRA L. Static Balance in Young Children. CHILD DEVELOPMENT, 1984, 55, 854-857. The purpose of this study was to describe the static balance ability of 6-9-year-old children. A 32-item test battery was administered to 154 subjects.

On the Impedance of Statically-Balanced Mechanisms

Volume 6: 35th Mechanisms and Robotics Conference, Parts A and B, 2011
Statically-balanced technology is often used to compensate partial or full gravity force exerting on a mechanism in order to reduce the effort of driving the mechanism. Since such compensation is static, when a statically-balanced mechanism is used for dynamic applications, it will still have impedance (mechanical resistance to input motion) because ...

Static balance and developmental coordination disorder

Human Movement Science, 2003
The development of static balance is a basic characteristic of normal motor development. Most of the developmental motor tests include a measure of static balance. Children with a developmental coordination disorder (DCD) often fail this item. Twenty-four children at risk for DCD with balance problems (DCD-BP) and 24 matched control children in the age

Static Balancing of Tensegrity Mechanisms

Volume 7: 29th Mechanisms and Robotics Conference, Parts A and B, 2005
The computation of the equilibrium configurations of tensegrity mechanisms is often a very tedious task even for relatively simple architectures. However, it has been observed that the complexity of this problem is significantly reduced when gravitational loads are compensated with the use of static balancing techniques.

Static and Dynamic Balance Control in Older Golfers

Journal of Aging and Physical Activity, 2010
Purpose:To determine whether older golfers have better static and dynamic balance control than older but nongolfing healthy adults.Methods:Eleven golfers and 12 control participants (all male; 66.2 ± 6.8 and 71.3 ± 6.6 yr old, respectively) were recruited. Duration of static single-leg stance was timed.

Spatial Static Gravity Balancing With Ideal Springs

Volume 2: 28th Biennial Mechanisms and Robotics Conference, Parts A and B, 2004
This paper discusses mechanisms that allow for perfect static balancing of rotations about a fixed spherical joint by means of ideal springs. Using a potential energy consideration, balancing conditions of a spatial three-spring balancer will be derived.

Static Balancing of Centrifugal Fan

IOSR Journal of Mechanical and Civil Engineering
Centrifugal fans are critical in cement manufacturing for airflow regulation and dust management but often suffer from vibration-related faults due to harsh operational conditions. Excessive vibration, commonly caused by rotor unbalance and misalignment, can lead to premature component failure.

Static balancer for the rectilinear motion

2013 13th International Conference on Control, Automation and Systems (ICCAS 2013), 2013
This paper presents static balancers for a rectilinear motion using springs. A slider-crank mechanism is adopted as a base mechanism and is considered as a two-link and two-dof (degree of freedom) manipulator with an external load at the end-effector. The design of a gravity compensator is considered as mapping unit spring balancers to the slider-crank

Static phase improvements in the LNE watt balance

Review of Scientific Instruments, 2016
This paper describes the mechanical and electrical modifications carried out on the LNE watt balance to reduce the noise level associated with the static phase. The mechanical improvements concern the home-made balance beam using flexure hinges as pivots of the force comparator.
