The truss rod counteracts the immense amount of tension the strings place on the neck, bringing the neck back to a straighter position.

Turning the truss rod clockwise tightens it, counteracting the tension of the strings and straightening the neck or creating a backward bow.

Turning the truss rod counter-clockwise loosens it, allowing string tension to act on the neck and creating a forward bow.

They differ from the archetypical tie rod by both pushing and pulling ( operating in both tension and compression ).

Changing the pitch of a timpani by turning each tension rod individually is a laborious process.

Hooke's law of elasticity states that the extension of an elastic rod ( its distended length minus its relaxed length ) is linearly proportional to its tension, the force used to stretch it.

" These may have a vertical tension rod that extends to the ceiling to provide extra stability.

The tension on the foreskin by DTR depends mainly on the size of the shaft rod and the size & strength of the rubber band.

TLC-X has a pusher inside the cones to provide bi-directional tension and a rod for attaching weights or rubber bands for strapless tension.

It consists of a shaft ( tension rod ) with a pusher plate and a bell with a silicone gripper, the bell can move on the shaft and has a collet to hold it in place.

The collet easily slides up the tension rod, staying where it is placed, until being manually repositioned for more or less tension.

Originally a rope-tensioned drum, giving way to modern rod tension, the tenor drum occupied a unique position in the drum corps of military and civilian pipe bands, being used as both timekeepers, accents to the musical ensemble, as well as spectacle.

The repaired eyebar was placed under tension and the temporary block and tie rod assemblies were removed.

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

It is used to correct changes to the neck's curvature caused by the neck timbers aging, changes in humidity or to compensate for changes in the tension of strings.

* Crimp the bullet in place ( optional ; some may hold the bullet with neck tension alone )

Inconsistent neck thickness and neck tension will result in variations in pressure during ignition.

A rubber balloon, inflated but not tied off and stretched tightly across the neck produces a squeak or buzz, depending on the tension across the neck and the level of pressure inside the balloon.

The term steel guitar should not be confused with steel-strung guitar, which is a standard acoustic guitar that has steel rather than the nylon, cat-gut or brass / nickel strings used for classical guitar or standard acoustic guitar, and is built with extra bracing, a stronger neck, and higher-geared machine heads to compensate for the much higher tension of steel strings.

Adjustment / manipulation has been shown to help with low back pain, neck pain and tension type headaches, but further studies are inconclusive on the use of spinal manipulation outside the treatment of neuromusculoskeletal disorders.

Spasmolytics such as carisoprodol, cyclobenzaprine, metaxalone, and methocarbamol are commonly prescribed for low back pain or neck pain, fibromyalgia, tension headaches and myofascial pain syndrome.

As the tension mounted, Tex tied up Folger's hands with a section of rope that bound Sharon's neck.

Tension headaches may be caused by muscle tension around the head and neck.

A 2004 Cochrane review found that spinal manipulation may be effective for migraine and tension headache, and that spinal manipulation and neck exercises may be effective for cervicogenic headache.

A proper garment is shaped from the neck to the chest and shoulders to drape without wrinkles from tension.

The tension on the neck-rope can only be relieved if the victim keeps their neck, back and legs arched ; eventually, the victim tires and strangles.

The shoulders are relaxed with a sense of a gently drawing down action of the shoulder blades to stabilise the scapular and release neck tension.

It necessitated that Gautreau stand with her body facing the artist while her head was turned away, her right arm extended behind her for support, her hand on a low table ; the result was to create tension in the neck and arm as well as to emphasize the subject's elegant contours.

However, thanks to excellent stability and reaction to string tension and pressure, neck through guitars are often much more sturdy than many other guitars on the market.

He described it as a mild condition, a tension headache possibly accompanied by neck or wrist pains, caused by unhealthily long reading sessions of Harry Potter.

* Necking ( engineering ), the process by which a ductile material deforms under tension forming a thin neck

In 1865, after much agitation and tension, the colonial office replaced the elective assembly with one composed of one-half elected members and one-half appointed.

This has the function of a corner post and brace assembly but handles tension from opposite sides.

Typically, the pedal is connected to the tension screws via an assembly of either cast metal or metal rods called the spider.

When the assembly cooled the mask was under great tension, which no amount of heating from the guns would be able to remove.

At this session tension was so high between politicians that fighting ensued in the assembly following communist deputees speeches against the Indochinese policy.

Bi-oriented sister kinetochores stabilize the kinetochore-microtubule assembly whereas weak tension has a destabilizing effect.

The thousands of city migrants who desert the farms yearly must readjust with even greater stress and tension: the sacred wilderness is gradually surrendering to suburbs and research parks and industrial areas.

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

This is possible with water and other liquids that have a high surface tension.

Belt tension is adjusted by manipulation of two locking bolts and a movable motor mount.

The return spring tension may be adjusted to suit individual requirements by gripping the spring housing with a pair of pliers ( to prevent the spring from unwinding when it is released ), loosening the lock nut or screw, and rotating the housing until the desired tension is achieved.

Essentially these birefringence studies show that at low rates of shear a tension is present at 45-degrees to the direction of shear, and as the rate of shear increases, the direction of the maximum tension moves asymptotically toward the direction of shear.

The direction of the tension of minimum pressure is, of course, given by the direction of the major axis of the ellipsoids.

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.

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.
