We can use this fact to find the conditions for "static equilibrium": the condition an object is in when there are forces acting on it, but it is not moving. The conditions for static equilibrium are easy to state: the sum of the (vector) forces must equal zero, and the sum of the torques must equal zero:

A standard definition of static equilibrium is: This is a strict definition, and often the term "static equilibrium" is used in a more relaxed manner interchangeably with "mechanical equilibrium", a...

Static Equilibrium; An object is in static equilibrium (it is not moving) IF; 1) it is not translating (not moving up, down, left, or right) AND; 2) it is not rotating (not spinning CW or CCW); (We are talking about motion in a 2D plane here.);

CTSE-1. A mass m is hung from a clothesline stretched between two poles. As a result, the clothesline sags slightly as shown. ... The tension T in the clothesline has magnitude.. ... The y-component of each tension vector must be Ty = mg/2 , since the upward forces (2Ty) must cancel the downward force (mg).  If the angle of...

Predict and confirm different vertical forces during static equilibrium (Net Forces = 0) ... 1. Static Equilibrium exists when the Net Forces on an object total zero (cancel each other out). The sum of all vertical Force vectors equal zero, and the sum of all horizontal Force vectors equal zero. Today your assigned mass...

The concept of torque is useful in determining whether or not a given object will be in static equilibrium. Consider two children, each of mass 30 kg, sitting on a teeter-totter as below.
