	Angle of incidence - Wikipedia, the free encyclopedia
		An angle of incidence is the angle between a beam incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal.
		The angle of incidence at which light is first totally internally reflected is known as the critical angle.
		It should not be confused with the angle of attack, which is the angle the wing chord presents to the airflow in flight.

	Running rigging - Wikipedia, the free encyclopedia
		Running rigging is the term for the rigging of a sailing vessel that is used for raising, lowering and controlling the sails - as opposed to the standing rigging, which supports the mast and other spars.
		Traditionally the running rigging was easily recognized, since for flexibility it was not coated with tar and therefore of a light color, while the standing rigging was tarred for protection and therefore fl or dark in color.
		On modern vessels, running rigging is likely to be made from nylon and other synthetic fibers, while the standing rigging is frequently made of steel cable, for strength.

	Sailing - Wikipedia, the free encyclopedia
		Depending on the efficiency of the rig, the angle of travel can be as little as 35 degrees (half of a 70 degree tacking angle) to over 70 degrees[1].
		Some non-traditional rigs capture energy from the wind in a much different fashion, and are capable of feats that traditional rigs are not, such as sailing dead into the wind.
		In modern parlance, a brigantine is a vessel whose forward mast is rigged with square sails, while her after mast is rigged fore-and-aft.

		The rigging objective being to adjust the boat to comfortably fit the rower whole maintaining maximum efficiency of the rowing stroke.
		The angle can be decreased by either moving the keel only attachment and reading the scale on the older style foot stretcher or by moving the two bottom bolts attaching the bottom support bar on the newer stretcher.
		Height on either stretcher is changed by loosening either a single screw in the case of the older stretcher and moving to a new position or loosening and repositioning a new set of holes for the newer design.

		The angle at which a sling holds a given load influences the effective weight of the load.
		As shown in figures B-D, increasing the angle of the sling to the hook from 30 to 60 degrees increases the effective mass of the load from 1154 lbs to 2000 lbs, essentially doubling the weight on each leg of the sling at 60 degrees.
		Further, such changes in sling angle must be accounted for in lifts that are close to the sling weight limit and/or for critical lifts (greater than 90% of the crane limit).

	OKoffroad.com - Editorial - Winch Rigging
		The angle pull is used when something is causing an obstruction preventing a direct pull, or when the winching vehicle cannot be positioned for a direct pull.
		The use of a spreader bar placed in the V of the chain, close to the vehicle, is recommended to prevent the frame rails from collapsing inwards during the pull.
		The correct method to use to secure your rig and prevent damage to the frame, is to use two recovery points on the front of your rig and run the rigging under your vehicle and back to an anchor point.

	Rigging With Slings: Basic hitches, Working Load Limits, Sling angle, Reach
		The angle at which a sling is used, and the number of legs lifting the load can significantly effect its capacity.
		at an angle during a lift, the sling capacity is reduced.
		This is due to the difficulty of rigging a quad leg chain sling so that all legs share the load equally.

	Hanes Supply - Wire Rope Lift Engineering
		Multiplying this angle (known technically as the "half included angle") by TWO yields the leg angle that is used to calculate the ACTUAL Load on each leg of the bridle.
		Angles greater than 60 degrees not only build up tension in the sling legs out of all proportion to the weight of the load, they also create a much greater "in-pull" on the ends of the load.
		Angles greater than 60 degrees indicate some thought should be given to the use of a lifting beam or other device in connection with the lift.

	Concept 2 - Rigging with Dressigacker Oars
		Rigging is one of the most crucial aspects of rowing, and one of the most misunderstood.
		By rigging appropriately for the size, strength and ability of the athlete, you can optimize speed, technical performance, comfort, and most importantly, the pleasure of rowing.
		Catch angle is at the catch or beginning of the stroke; finish angle is at the finish or end of the stroke.

		Coincident with the airspeed decrease was an increase in pitch angle and angle of attack.
		About 10 seconds later, the angle of attack again increased and reached a value of +12.1 degrees as the pitch angle was reducing through 3 degrees; again, the stall warning was activated and the angle of attack reduced.
		In addition as the rigging pin and principle is similar on the yaw autopilot actuator, the same incorrect rigging could be introduced during adjustment of this actuator, such an incorrect rigging could generate yaw jerk at A/P disconnection.

	Rigging a Biplane - Conrad J. Morgan
		The reason is that the wing would then be too near the stalling angle and any inaccuracy in the rigging or other factors that may enter into the scheme of things, such as bounces and the like, would cause the wing to stall.
		If too much stagger is rigged into the ship, it immediately becomes tail heavy because you have moved the upper wing too far in front of the center of gravity.
		It is of utmost importance that the tail assembly be properly rigged.

		This means that the rotation values of the joints will stay within a limited range, and to get to the desired angle the X, Y and Z axis may jump from 180 to -180 in a single frame.
		What this does is find the angle between the joint in the bind pose, and the one you've placed it in, and uses that to drive the shape using an expression and some extra nodes.
		Note that this will create a spherical fall-off from the extreme of the pose, so if you go beyond the angle of the pose, or to the left or right of it, when animating the shape will be weighted down.

	Rigging Control Horns in 1/72nd [Archive] - The Aerodrome Forum
		When you start a monofilament from a hole and run it at a right angle from the hole,it has a tendancy to curve out of the hole rather than make a sharp,crisp angle.
		To glue the rigging line on the horns or at the ending point, I use a fine tweezers and hold the line very near the horn.
		Next, I fix the rigging line at one extremities, slip 1 or 2 "turnbuckles" on the line (it depend of the model) and fix the line at its other extremities.

		The aerofoils are arranged so that they are symmetrical and have zero rigging angle, that is, the angle that the aerofoils are set relative to the structure on which they are mounted.
		Relative to the airflow due to the wind, this creates a small positive angle of attack to the airflow, thus generating lift.
		As the aerofoil moves around the back of the apparatus, the angle of attack changes to the opposite sign, but the generated lift is still positive and in the direction of rotation, because the wings are symmetrical and the rigging angle is zero.

	Rigging with Slings page 2/2. Determining load. Unequal legs. Three and four legs. Choker Hitch.
		- When lifting or turning a load rigged with a choker hitch, the angle at which a sling is turned back on itself can reduce it's capacity below what is listed for its choker hitch, if the angle is too severe.
		When a load is allowed to hang free, the natural choke angle is about 135°.
		If the angle is less than 120°, you must adjust its Choker Hitch Working Load Limit by the appropriate choke factor from this table.

		To quickly determine whether your sling angle will be 60° or greater, lay a sling across the top of the sign cabinet.
		A sign should be rigged to yield a sling angle of at least 60° because, at this angle, the vertical-load angle factor increases by only about 15%.
		But, when the sling angle is 45°, the load-angle factor multiplies the vertical lifting force by more than 40%.
