A weight on two stringsPhysics · Class 11
The idea behind it
NCERT § "Equilibrium of a Particle"
- A particle is in equilibrium when the net external force on it is zero; it is then at rest or in uniform motion.
- Two forces keep a particle in equilibrium only if they are equal in size and opposite in direction.
- Three concurrent forces in equilibrium add to zero and can be drawn head to tail as a closed triangle.
- In practice, resolve every force along two perpendicular axes and set the sum of components along each axis to zero.
- A mass hanging from two strings is the standard case: the vertical components of the tensions together balance the weight, and the horizontal components cancel.
