How does the input distance of a single fixed pulley compare to the output distance?
The input distance of a single fixed pulley is equal to the output distance. The pulley system doesn't provide a mechanical advantage in terms of distance but does change the direction of the force applied.
What are the input arm output arm and fulcrum of a pulley?
The input arm is the distance between the input force and the fulcrum. The output arm is the distance between the output force and the fulcrum. The fulcrum is the fixed point around which the pulley rotates.
What is the ideal mechanical advantage and the direction of the input and output for a fixed pulley?
The ideal mechanical advantage of a fixed pulley is 1, as it does not provide any mechanical advantage in terms of force. The direction of the input (effort) and output (load) for a fixed pulley is the same, as the pulley simply changes the direction of the force applied.
What is velocity ratio of 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.
What is the relationship between the distance objects are lifted off the ground from a pulley to the distance the rope is pulled?
The distance an object is lifted off the ground is equal to the distance the rope is pulled when using a pulley system. This is due to the principle of work conservation, where the work input is equal to the work output, assuming no energy losses.

Type of pulley that has additional numbers of ropes that help to increase mechanical advantage?
Fixed Pulley!!
What are the differences between a fixed pulley and a moving pulley and how do each of them change work?
A fixed pulley is stationary and changes the direction of the force applied, making it easier to lift an object. A moving pulley is attached to the object being lifted, reducing the force needed but requiring a longer distance to be moved. Both types of pulleys reduce the amount of work needed by spreading it out over a longer distance or making it easier to lift the load.
What is the mechanical advantage of a single fixed pulley?
The mechanical advantage of a single fixed pulley is 1. This means that the input force is equal to the output force, making the pulley useful for changing the direction of the force applied.
How far must the effort rope of a single fixed pulley move to raise a resistance 4m?
In a fixed pulley system, the effort rope must move the same distance as the resistance (4m) in order to raise it by the same amount. This is because the fixed pulley changes the direction of the force applied, but does not provide any mechanical advantage in terms of distance.
The mechanical advantage of a single fixed pulley is always one because why?
The mechanical advantage of a single fixed pulley is always one because it changes the direction of the force applied without providing any leverage to increase the force. This means that the input force is the same as the output force, resulting in a mechanical advantage of 1.
Why does a fixed pulley provide only a mechanical advantage of 1?
A fixed pulley changes the direction of the force applied without providing any mechanical advantage. The input force is equal to the output force, resulting in a mechanical advantage of 1. Fixed pulleys are mainly used to change the direction of force rather than to increase the force.
Is the output force greater than the input force for a pizza cutter a hockey stick a single fixed pulley or a screw?
The output force is greater than the input force for a single fixed pulley. This is due to the mechanical advantage provided by the pulley system. For a pizza cutter, hockey stick, and screw, the output force is typically equal to or less than the input force.
