Question

A 14 lb. teapot hangs by two massless ropes attached to the ceiling, each at a 45 degree angle. If the teapot isn't moving, it is in static equilibrium. We know that the net force on the teapot must be zero. Since there is a 14 lb. force down on the teapot (its weight), where does the missing force to somehow add up to zero come from and what is the force of the massless ropes?

Answer #1

Soln:- teapot will not move because its weight is balanced by tension of ropes .

This tension came into play due to weight of teapot . We know that weight of teapot wants to pull teapot down but since it is hanged by ropes so it will pull these ropes too . since ropes are hinged on roof so they don't go down and pull block teapot with same force .so a tension will be there which is pulling force of ropes .
