one example of a single pulley is a clothes line . another example is a ................ what do you think because I need to think more on this.
single fixed pulley, single movable pulley and single fixed and movable pulley. :-)
E=l/2 2=l/e or l/e=2 ma =l/e ma of single moveable pulley is : l/e=2
Depending on how the pulley is mounted and how the rope is strung, the M.A. of a set-up with a single pulley is either ' 1 ' or ' 2 '.
Single Pulley
A simple single pulley enables the applied force to change direction. A pulley at the top of a well is the common example. In many applications, such as the fan belt on a car, it is used to transfer energy from one shaft to another.
A single movable pulley has a mechanical advantage of 2 because it reduces the effort needed to lift an object by half. This is due to the pulley system allowing the weight to be distributed between the weight being lifted and the tension in the supporting rope.
Nothing, really. A slight loss due to friction. If the pulley is fixed to the load, then there is a 2:1 advantage.
A fixed pulley, where the pulley is attached to a support and only changes the direction of the force applied. And a movable pulley, where the pulley is attached to the object being moved and reduces the effort required to lift the load.
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.
Single movable pulley
Single fixed pulley
One single fixed pulley cannot give any mechanical advantage. It can only redirect the direction of the applied force.
