What is the relationship between the distance objects are lifted off the ground from a pulley to the distance the rope is pulled?
There are two cases:If the pulley is fixed to an overhead beam then the distance the object moves will be the same as the distance that the rope is pulled.If one end of the rope is fixed to an overhead beam and the pulley is free to move then the distance the object moves will be one-half the distance that the rope is pulled.
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
The difference between a fixed pulley and a movable pulley is, the wheel of a fixed pulley does not move because the wheel is attached to a wall, ceiling, or other object. Unlike a fixed pulley, a movable pulley's wheel does move. The wheel on a movable pulley is not attached to a wall or other object. A fixed pulley changes work by changing the direction of a force. A movable pulley changes work by reducing the input force needed to lift heavy objects. A movable pulley changes the direction of the input force and reduced it. A movable pulley also increases the output force.

Why is the mechanical advantage of a simple fixed pulley always 1?
Because the input work equals the output work
What is the output force exerted by a move-able pulley if the input force is 50 N?
The answer will depend on the configuration of the rope as it goes around the movable pulley and the fixed roller.
Type of pulley that has additional numbers of ropes that help to increase mechanical advantage?
Fixed Pulley!!

The answer will depend on the configuration of the rope as it goes around the movable pulley and the fixed roller.
What happen as the volume of output decreases?
Fixed costs per unit will increase.
Do the fixed costs increase as output increases?
No these are costs such as rent stay basically same irrespective of output
Total variable cost does not increase in proportion to output is it true?
False, it is the fixed cost which is not increased or decreased with proportion to output.
How far must the effort rope of a single fixed pulley move to raise a resistance 4m?
4m. A single fixed pulley only controls the direction, but has no effecton the force, or on the distance that the ends move.
What is an example of a fixed pulley?
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.
Kind of pulley that is not movable?
The major two types of simple pulleys are movable and fixed. An example of a fixed pulley would be a flag pole. The pulley is fixed in place while someone pulls on one end of the rope to lift the flag on the other end, the input force and the output forces being equal in magnitude but opposite in direction.
