 ## Ant on a Tightrope University of Iceland NASA Technical Memorandum Z ' r-). An object accelerates toward the Earth at a rate of 32 feet per second per second, or 32 ft/sВІ, irrespective of its mass. Scientists refer to this as the acceleration due to gravity. The concept of GвЂ™s, or вЂњG-forces,вЂќ refers to multiples of the acceleration due to gravity and the concept applies to acceleration in any, To avoid passengers in transportation losing control over their body motion, thereby endangering their physical integrity, it is not only necessary to limit the maximum acceleration, that is the force, they can safely be exposed to, but also the maximum jerk, since they need time to adapt to even limited stress changes by adjusting their muscle.

Tolerance to brief impact is related to the imposed velocity change, whilst in longer impacts it is the level of acceleration which is critical. This behaviour results from the dynamic characteristics of the body which, for practical purposes, can be represented as a simple mass spring system., To avoid passengers in transportation losing control over their body motion, thereby endangering their physical integrity, it is not only necessary to limit the maximum acceleration, that is the force, they can safely be exposed to, but also the maximum jerk, since they need time to adapt to even limited stress changes by adjusting their muscle.

Acceleration tolerance is a complex concept which is frequently associated with a certain amount of misunderstanding. Acceleration research may involve different aspects of acceleration tolerance depend-ing upon the major interest of that research, however the entire scope of the tolerance envelope must al-ways be considered. Ant on a Tightrope; A large ant is standing on the middle of a circus tightrope that is stretched with tension . The rope has mass per unit length . Wanting to shake the ant off the rope, a tightrope walker moves her foot up and down near the end of the tightrope, generating a sinusoidal transverse wave of wavelength and amplitude .

Acceleration and forces. The term g-force is technically incorrect as it is a measure of acceleration, not force. While acceleration is a vector quantity, g-force accelerations ("g-forces" for short) are often expressed as a scalar, with positive g-forces pointing downward (indicating upward acceleration), and negative g-forces pointing upward. Centrifuges are often rated in terms of their centripetal acceleration relative to acceleration due to gravity \((g)\) maximum centripetal acceleration of several hundred thousand \(g\) is possible in a vacuum.

Set the acceleration equation equal to zero and solve for time. More than one solution may exist, which is fine. Remember acceleration is the slope of the velocity equation and the derivative is just the slope of the original line. When the slope is equal to zero, the line is horizontal. This occurs at an extremum, i.e., a maximum or a minimum.

11. Tolerance: The term tolerance refers to the difference between the upper (maximum) limit and lower (minimum) limit of a dimension. In other words, tolerance is the maximum permissible variation in a dimension. The tolerance may be of two types i.e. unilateral or bilateral. Because acceleration is constant I can expect a linear velocity equation. What is confusing me is that we are to assume constant acceleration. Thus the acceleration equation will merely be some real number. So, what exactly is expected if it is to be in terms of g? Is my strategy to find acceleration incorrect?
