It places terrific tension on the leg muscles from start to finish of each repetition.

excess tension will only cause undue wear on the motor and spindle bearings.

The relative forces can be calculated from the various radii of curvature if we assume: ( A ) The surface tension is uniform on the surface of the drop.

Just as the pressure exerted by surface tension in a spherical drop is Af and the pressure exerted by surface tension on a cylindrical shape is Af, the pressure exerted by any curved surface is Af, where **yg is the interfacial tension and Af and Af are the two radii of curvature.

Anne laughed and Cady felt the tension loosen its grip on the back of his neck.

On this basis, he argues that ethics must focus on ' dialectically integrating opposites ' and balancing tension, rather than seeking a priori validation or certainty.

The HAM-A ( Hamilton Anxiety Scale ) measures the severity of a patient's anxiety, based on 14 parameters, including anxious mood, tension, fears, insomnia, somatic complaints and behavior at the interview.

A hand on the anchor line may telegraph a series of jerks and jolts, indicating the anchor is dragging, or a smooth tension indicative of digging in.

After both anchors are set, tension is taken up on both cables to limit the swing or to align the vessel.

When a tyrannosaur would have pulled back on a piece of meat, the force would tend to push the tip of tooth toward the front of the mouth and the anchored root would experience tension on the posterior side and compression from the front.

The matches are known for their tension and violence, both on and off the pitch.

They consist in two plates bonded on a limited length and loaded in tension on both ends.

The arguments for this generally rely on crude mechanical reasoning, such as claiming that a lower tension string bed is more bouncy and therefore provides more power.

An alternative view suggests that the optimum tension for power depends on the player: the faster and more accurately a player can swing their racquet, the higher the tension for maximum power.

There are several factors involved in producing different pitches on a brass instrument: One is alteration of the player's lip tension ( or " embouchure "), and another is air flow.

Equations which define the shape of the curve and the tension of the chain at each point may be derived by a careful inspection of the various forces acting on a segment using the fact that these forces must be in balance if the chain is in static equilibrium.

Diagram of forces acting on a segment of a catenary from c to r. The forces are the tension T < sub > 0 </ sub > at c, the tension T at r, and the weight of the chain ( 0, − λgs ).

It is equipped with electronic controls that can be set to hold precise tension and speed.

To increase faculty influence and decrease tension, many presidents have established a standing advisory committee with which they can discuss problems frankly.

If it is assumed that the formula given by Lodge of cosec Af applies, the pressure difference along the major axes can be calculated from the angle of inclination of the major axis, and from this the interfacial tension can be calculated.

In addition, dirt particles can be held onto a soiled surface by sticky substances or by the surface tension of liquids, including liquid greases.

This property refers to the greatest longitudinal stress or tension a material can endure without tearing apart.

Anxiety can also be experienced in ways which include changes in sleeping patterns, nervous habits, and increased motor tension like foot tapping.

In the period of 3 – 6 weeks following cessation increased anxiety, depression as well as sleep disturbance is common ; fatigue and tension can persist for up to 5 weeks as part of the post-acute withdrawal syndrome ; about a quarter of alcoholics experience anxiety and depression for up to 2 years.

This is in fact incorrect, for a higher string tension can cause the shuttle to slide off the racquet and hence make it harder to hit a shot accurately.

To consider but one example, the First Amendment to the United States Constitution states " Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof "— but interpretation ( that is, determining the fine boundaries, and resolving the tension between the " establishment " and " free exercise " clauses ) of each of the important terms was delegated by Article III of the Constitution to the judicial branch, so that the current legal boundaries of the Constitutional text can only be determined by consulting the common law.

) is idealized by assuming that it is so thin that it can be regarded as a curve and that it is so flexible any force of tension exerted by the chain is parallel to the chain.

In an elastic catenary, the chain is replaced by a spring which can stretch in response to tension.

First, let T = T ( s ) be the force of tension as a function of s. The chain is flexible so it can only exert a force parallel to itself.

Controversial issues are held as potentially divisive in a given society, because they can lead to tension and ill will, as a result they are often taboo to be discussed in the light of company in many cultures.

The head's tension can be adjusted by loosening or tightening the rods.

When the hoop is placed around the drum head and shell and tightened down with tension rods, the tension of the head can be adjusted.

A " non-ionic " surfactant solution can become self-contained under the force of its own surface tension, remaining in the shape of its previous container for some time after the container is removed.

The surface of a glass is often smooth since during glass formation the molecules of the supercooled liquid are not forced to dispose in rigid crystal geometries and can follow surface tension, which imposes a microscopically smooth surface.

These harps can only play in a single key during any given performance, though any string on a harp can be tuned to a corresponding sharp or flat before a performance and then be returned to its regular tension ( key ) afterwards with little effort.

The spring tension controls the amount of pressure required to lower the top cymbal, and how fast it returns to its open position, and can also be varied.

The relationship between the author and the editor, often the author's only liaison to the publishing company, is often characterized as the site of tension.

There are only two specific exercises practiced separately ; the first is lying semi-supine ; resting in this way uses " mechanical advantage " as a means of releasing cumulative muscular tension.

Replacement grips have an adhesive backing, whereas overgrips have only a small patch of adhesive at the start of the tape and must be applied under tension ; overgrips are more convenient for players who change grips frequently, because they may be removed more rapidly without damaging the underlying material.

Temperature affects not only the viscosity, but also interfacial tension in the case of non-ionic surfactants or more generally interactions forces inside the system.

Second, integral reinforcing steel gives modern concrete assemblies great strength in tension, whereas Roman concrete could depend only upon the strength of the concrete bonding to resist tension.

Furthermore the crossbow could hold the tension for a long time, whereas even the strongest longbowman could only hold a drawn bow for so long.

The writer Elizabeth Hardwick recalled how intoxicating a performer he was and how the tension would build before a performance: " Would he arrive only to break down on the stage?

" Thales of Miletus, who lived from 625 – 547 ( BCE ) was the only documented person who believed that earthquakes were caused by tension between the earth and water.

Temperature affects not only the viscosity, but also the interfacial tension in the case of non-ionic surfactants, or on a broader scope, interactions of forces inside the system.

As it relies on gravity to close the cymbals, the drop clutch gives the player no control over the tension holding them together, and supplies only minimal tension.

If the spheres only appear to rotate ( that is, we are watching stationary spheres from a rotating frame ), the zero tension in the string is accounted for by observing that the centripetal force is supplied by the centrifugal and Coriolis forces in combination, so no tension is needed.

Some precision or fragile objects — such as passengers, who need time to sense stress changes and adjust their muscle tension or suffer conditions such as whiplash — can be safely subjected not only to a maximum acceleration, but also to a maximum jerk.

Following the tension of Game Six, the Cardinals pitching and defense came undone in Game 7 and their offense was shut down by Saberhagen leading to the lowest batting average to date (. 188 by the Cardinals, later broken by 2001 Yankees ) and fewest runs ( 13 for the Cardinals, still stands ) of any team in a 7 game series, and the Royals won 11 – 0 to clinch the franchise's only World Series title.

In a modern installation, the magneto only has a single low tension winding which is connected to an external ignition coil which not only has a low tension winding, but also a secondary winding of many thousands of turns to deliver the high voltage required for the spark plug ( s ).

Gorbachev's extension of regional autonomy only fueled existing ethnic / regional tension, while Deng's reforms did not alter the tight grip of the central government on any autonomous regions.
