Using Kinetics to Determine Slip Probability in a Movement Associated with a High Risk of Slip Occurrence
… may be possible to evaluate only one component, horizontal force, of the current friction calculation. The purpose of this dissertation was to determine if horizontal force generation would serve as a more accurate predictor of slip probability for movements associated with a high-risk of …

Lateral collapse potential of wood pallets
… model was developed to predict the maximum horizontal force a pallet can sustain. A simple equilibrium of forces approach including joint rigidity was used. A lateral load test machine was built which induces and measures the amount of horizontal force required to collapse a pallet. After …

The Mechanics of Regaining Balance in Pirouettes
… above the supporting foot (SF), which requires a horizontal force on the body from the floor; (2) Hop the SF to a position vertically under the CM, which compromises the aesthetic of the movement; or (3) slide the SF under the CM, which moves the area of support and produces a horizontal force to …

Blade dynamics and flux measurements for model seagrass blades in waves and currents
… studies of LDPE, the balance of the drag force due to fluid motion and the restoring force due to blade stiffness determined the blade posture in unidirectional flow and the relative motion in oscillatory flow. The blade rigidity was adjusted by changing either the blade length or the …

Analysis of Anchors and Bracing Configurations for Personal Fall Arrest Systems in Residential Construction
… points and bracing configurations loaded by a horizontal force. A lab built roof system was used to test three different anchor types with three forms of temporary bracing. The materials and methodology used in this testing were based on common materials and practices currently used in the …

Development of a corn stover yield monitor
… with load cells to measure the impact force of the corn stover on the impact plate. Instrumentation methods for the impact plate were evaluated to determine the most effective method to instrument the impact plate to measure the impact force of the stover.</p> <p>Field testing was …

Finite Element Analysis of Single Plate Shear Connections
… criteria result in connections with significant horizontal forces at the bolts. This horizontal force reduces the shear strength of a bolt group and creates a moment that must be considered in design. The magnitude of the force depends on the location of the bolt with respect to the beam neutral …

The relationship between stem-form, stand-closure and site -conditions : the influence of environmental conditions on tree allometry and forest structure in west-central Alberta
… by stem-fo~, is the result of the vertical force of gravity and the horizontal force of wind. The effect of wind force is demonstrated in the relationship between stem-form, standclosure and site-conditions. An increase in wind force on the individual tree due to a decrease in stand density …

Lower Limb Fatigue Asymmetry of Preferred and Non-Preferred Legs after a Repeated-Sprint Test in Football Players with Previous Hamstring Injury
… the accumulation of fatigue, and that inter-limb force production variation increases as fatigue progresses. Thus, the possibility exists that increases in inter-limb force production variability after fatiguing exercise would increase injury risk in football players. The purpose of the present …

Experimental Study of Tsunami-Induced Loads on Bridges
… lack of general agreement even on the types of forces imposed on the bridge decks. Reviewing the available literature revealed that the magnitudes of the actual tsunami loads on coastal structures and bridges are usually not accurately known. It emphasises the need for more investigation of …

Measurement of performance and kinetics during a change of direction, offensive and defensive agility task : a comparison of male and female athletes
… foot RT test required subjects to leap off a force plate to the appropriate mat in response to the stimulus, with RT, movement time (MT) and total movement time (TMT), being measured. Intra-class coefficient, coefficient of variation, and paired samples t-test (p ≤ 0.05) were calculated for …
