Vor 2 Tagen · The Young's modulus directly applies to cases of uniaxial stress; that is, tensile or compressive stress in one direction and no stress in the other directions. Young's modulus is also used in order to predict the deflection that will occur in a statically determinate beam when a load is applied at a point in between the beam's supports.
Vor 5 Tagen · In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise.

Vor einem Tag · The pressure is then defined as the average of the three principal stresses. The stresses in an electromagnetic field are generally non-isotropic, with the stress normal to one surface element (the normal stress ) being negative, and positive for surface elements perpendicular to this.

Vor 2 Tagen · Physics portal. Category. v. t. e. Newton's laws of motion are three laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows:
Vor 2 Tagen · General continuum equations. The Navier–Stokes momentum equation can be derived as a particular form of the Cauchy momentum equation, whose general convective form is. By setting the Cauchy stress tensor to be the sum of a viscosity term (the deviatoric stress) and a pressure term (volumetric stress), we arrive at.
Vor 5 Tagen · stress, in psychology and biology, any environmental or physical pressure that elicits a response from an organism. In most cases, stress promotes survival because it forces organisms to adapt to rapidly changing environmental conditions.
Vor 3 Tagen · Stress [englisch »Druck«, »Anspannung«, gekürzt aus distress »Sorge«, »Kummer«, letztlich zu lateinisch distringere »beanspruchen«, »einengen«] der, -es/-e, der Begriff bezeichnete ursprünglich Druck- und Spannungsverhältnisse im Naturbereich und dient in dieser Bedeutung heute noch in der Geologie zur Bezeichnung für ...
