Difference between fixed pulley and movable pilley , write into to halfs
Answers
A fixed pulley is one in which the drum is secured to a single spot. While the force required to lift or move an object is no different than if you were lifting it by hand, the fixed pulley allows you to change the direction of the force needed.
Thankyou
A fixed pulley is different from a movable pulley because a movable pulley has one end of the rope attached to it fixed on an unmoving object. The pulley is free to move with the rope. You pull the other end of the rope. Also, a movable pulley multiplies the applied force (effort force) and therefore has more mechanical advantage. A fixed pulley is attached to something that doesn't move, while one end of the rope is holding the weight, while the other is for pulling.
An example of a fixed pulley would be a well. This is a fixed pulley because the pulley doesn't move even though it is attached to an object.
