Question

If anybody is tied to three or more ropes, and then is allowed to achieve its equilibrium. Then the equilibrium achieved is achieved w.r.t what?

(a) The three axis of the body

(b) The ground

(c) The ropes direction

(d) The weight direction

I had been asked this question in exam.

I'd like to ask this question from Three Dimensional Force System in chapter Equilibrium of a Particle of Engineering Mechanics

Answer 1

Right option is (b) The ground

Easiest explanation: Yes, the equilibrium is being achieved w.r.t the ground. Like the motion, w.r.t ground need be zero. That is the relative velocity of the object or the body must be zero w.r.t the ground. This means motion is in equilibrium.
