Nothing, really. A slight loss due to friction. If the pulley is fixed to the load, then there is a 2:1 advantage.
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
Single Pulley
single fixed pulley changes the direction of the applied force, you pull down, the object goes up.
Single fixed pulley
To change the direction of pull.
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
Single Pulley
Single fixed pulley
single fixed pulley changes the direction of the applied force, you pull down, the object goes up.
Movable pulley is attache to the object you are moving while Fixed Pulley changes direction of the applied force.LaDy_caRoLi "Christine carren alcantara"
Single fixed pulley
A single fixed pulley (:
The velocity ratio of a single fixed pulley is 1. This means that the input and output speeds are equal. The pulley simply changes the direction of the force applied.
A single movable pulley is typically considered superior to a single fixed pulley because it reduces the amount of force needed to lift an object. The movable pulley changes the direction of the force applied, making it easier to lift heavy objects.
because lifes hard
a directional advantage
The Ideal Mechanical Advantage (IMA) of a pulley system is equal to the number of sections of rope supporting the load. In a simple pulley system with one pulley, the IMA is 1. If multiple pulleys are used in a system, the IMA is calculated by counting the number of strands supporting the load.
