What condition or conditions are necessary for static equilibrium?
a) E Fx =0
b) E Fx=0, E Fy=0, E T=0
c) E T=0
d) E Fx=0, E Fy=0
The correct condition or conditions necessary for static equilibrium are:
d) E Fx=0, E Fy=0
To understand why, let me explain the concept of static equilibrium first. In physics, static equilibrium refers to a situation where an object is at rest and is not accelerating. In other words, the net force acting on the object is zero, and the net torque (or moment) acting on the object is also zero.
To achieve static equilibrium, we need to consider the forces acting on the object in both the x-axis and y-axis directions. The conditions necessary for static equilibrium are:
1. E Fx=0: The algebraic sum of the forces acting in the x-axis direction (Fx) must be zero. This means that the forces pushing or pulling the object from left to right, or right to left, must balance each other out.
2. E Fy=0: The algebraic sum of the forces acting in the y-axis direction (Fy) must be zero. This means that the forces pushing or pulling the object upwards or downwards must balance each other out.
By satisfying both conditions (E Fx=0 and E Fy=0), we can ensure that the object remains at rest without any acceleration.
Therefore, option d) E Fx=0, E Fy=0 is the correct answer for the condition(s) necessary for static equilibrium.
