What is a fixed pulley?
A fixed pulley is a pulley that is attached to a support. It does not reduce the effort needed to lift the load, but rather changes the direction of the applied force.An example of a fixed pulley would be the rope pulley on a well. This is a fixed pulley because the pulley doesn't move (it is attached to the overhead structure).
What do we use a fixed pulley for?
this is berat writing.we use fixed pulley for lifting load up only by using force on the effort that makes the load lift
How does a fixed pulley make work easier?
A fixed pulley does not make the force applied easier, it changes the direction of this force. For example, instead of bending over and lifting and object, a fixed pulley lets you lift it by pulling down on a rope.
What is making it easier to lift the load?
The mechanical advantage of the block and pulley you are using, or the engine of the fork lift truck if that is what you are using.
24lbs of weight hanging on a pulley how much force is needed to lift the weight?
If the pulley is fixed (hanging from the ceiling), and the rope passes over it, then 100 lbs of force is required. If the rope is fixed to the ceiling and passes under the pulley (which is fixed to the load), then 50 lbs of force is required.
A fixed single pulley that is used to lift a block does what?
The choices are:A. Doubles the force required to lift the blockB. Decreases the force required to lift the blockC. Makes the block easier to lift by changing the direction of the force needed to lift it.D. Decreases the force required and changes the direction of the force required

Would you use a fixed pulley or movable pulley to lift a heavy load?
Fixed if it weighed as less than you, but a movable pulley wouldn't be helpful here. You'd be best with a pulley with multiple supporting ropes.

Does the force used to lift an object using a single pulley alter depending on the size of the pulley?
no
