resting length
(noun)
Often the ideal length of a muscle and the length at which it can create the greatest active force.
Examples of resting length in the following topics:
-
Rest Length
- For each kind of note, there is a written rest of the same length.
- For each note on the first line, write a rest of the same length on the second line.
- For example, in 3/4 time, a measure can have any combination of notes and rests that is the same length as three quarter notes.
- In this case, "whole rest" does not necessarily mean "rest for the same length of time as a whole note"; it means "rest for the entire measure".
- A whole rest may be used to indicate a completely silent measure, no matter what the actual length of the measure will be.
-
Dots, Ties, and Borrowed Divisions
- (See Duration:Note Length. ) The same goes for rests.
- (See Duration: Rest Length. ) But what if you want a note (or rest) length that isn't half of another note (or rest) length?
- One way to get a different length is by dotting the note or rest.
- Make groups of equal length on each side, by putting a dotted note or rest in the box.
- Any common note length can be divided into an unusual number of equal-length notes and rests, for example by dividing a whole note into three instead of two "half" notes.
-
Force of Muscle Contraction
- The force a muscle generates is dependent on its length and shortening velocity.
- The force a muscle generates is dependent on the length of the muscle and its shortening velocity.
- Skeletal muscles are attached to bones via tendons that maintain the muscle under a constant level of stretch called the resting length.
- If this attachment was removed, for example if the bicep was detached from the scapula or radius, the muscle would shorten in length.
- In mammals, there is a strong overlap between the optimum and actual resting length of sarcomeres.
-
Length Contraction
- Now imagine that the clock is at rest.
- Now, if someone in the ruler's rest frame wanted to determine the length of the ruler, they could do the following.
- For example, at a speed of 13,400,000 m/s (30 million mph, .0447c), the length is 99.9 percent of the length at rest; at a speed of 42,300,000 m/s (95 million mph, 0.141c), the length is still 99 percent.
- An observer at rest viewing an object traveling very close to the speed of light would observe the length of the object in the direction of motion as very close to zero.
- Observed length of an object at rest and at different speeds
-
Shifting the Paradigm of Physics
- Taking the muon lifetime at rest as the laboratory value of 2.22 μs, the lifetime of a cosmic ray produced muon traveling at 98% of the speed of light is about five times longer, in agreement with observations.
- For example the length contraction formula is:
- where $L_0$ is the rest length, the length of an object measured in the co-moving frame of the object, and $L$ is the length of the object as measured by the observer who sees the object moving at speed $v$.
- This altered the perception that the length of an object would appear the same regardless of the reference frame of the observer.
- Thus in every day life $\gamma \approx 1$ and we do not experience significant time dilation or length contraction.
-
Rhythmic Values
- Rests represent silence in musical notation.
- For each durational symbol there exists a corresponding rest.
- A dot occurs after a pitch or a rest, and it increases its duration by half.
- Ties are used to either sustain a pitch beyond the length of a single measure, or to make a particular rhythmic grouping in a measure more clear.
-
Duration: Note Lengths in Written Music
- (The extra time when the note could be sounding, but isn't, becomes an unwritten rest. ) If this is confusing, please see the explanation in articulation.
- All other note lengths are defined by how long they last compared to a whole note.
- You may have also noticed that the note lengths sound like fractions in arithmetic.
- Draw the missing notes and fill in the blanks to make each side the same duration (length of time).
- Whether a stem points up or down does not affect the note length at all.
-
The Simple Pendulum
- This is why length and period are given to five digits in this example.
- When a pendulum is displaced sideways from its resting equilibrium position, it is subject to a restoring force; after it reaches its highest point in its swing, gravity will accelerate it back toward the equilibrium position.
- We begin by defining the displacement to be the arc length s.
- When θ is expressed in radians, the arc length in a circle is related to its radius (L in this instance) by:
- The linear displacement from equilibrium is s, the length of the arc.
-
Pickup Notes and Measures
- The beats may be filled with any combination of notes or rests (with duration values also dictated by the time signature), but they must combine to make exactly the right number of beats.
- In this case, the first measure may be a full measure that begins with some rests.
- If there is a pickup measure, the final measure of the piece should be shortened by the length of the pickup measure (although this rule is sometimes ignored in less formal written music).
- (Of course, any combination of notes and rests can be used, as long as the total in the first and final measures equals one full measure.
- If a piece begins with a pickup measure, the final measure of the piece is shortened by the length of the pickup measure.
-
Multiple and logistic regression solutions
- The rest of the residuals do appear to be randomly distributed around 0.
- 8.13 (a) There are a few potential outliers, e.g. on the left in the total length variable, but nothing that will be of serious concern in a data set this large.
- For example, a possum's gender may be related to its head length, which would explain why the coefficient (and p-value) for sex male changed when we removed the head length variable.
- Likewise, a possum's skull width is likely to be related to its head length, probably even much more closely related than the head length was to gender.
- Only total length has a positive association with a possum being from Victoria.
