Question

VR of a single moveable pulley is always 2 why

Answer 1

Answer:

In a single fixed pulley, the velocity ratio is always more than the mechanical advantage.Now as we know that velocity ratio is defined as the ratio of distance travelled by the effort to the distance travelled by the load. So, velocity ratio of the single moveable pulley will be = Distance travelled by the effort FDistance travelled by the load L=2XX=2. As the velocity ratio is ratio.
