How many times a force is multiplied by a machine is the machanical?
The mechanical advantage.
What are the advantages of hydraulic brake compared to wires and pulleys?
Wires stretch and sag. Hydraulic fluids transfer force with far smaller losses.
What jobs did the pulley do?
A pulley is a wheel with a groove on its edge for holding a rope or cable. pulleys are usally used in sets desinged to reduce the amount or force needed to lift a load.
Where are pulleys used?
in wellsElevators, cranes, vacuums, and motors of all types, just to name a few.elevatersMany things uses a pulley. The Venetian blinds use a pulley to change the direction of force.
How can you increase mechanical advantage of a gear system?
A mechanical advantage occurs when a tool such as a hammer is used that increases the amount of force being applied without increasing the effort of the person using the tool. To increase mechanical advantage, you could use a bigger hammer to increase output force.
What force could increase the resistance of all the PULLEYS?
Any force that will not allow the pulley to operate to peak efficiency
How do you find the mechanical advantage of a simple machine?
To find the mechanical advantage of a simple machine divide output force by input force. (input force is the force that we exert on a machine, and output force is the force that is exerted by a machine).
How pulleys helps in pulling the water from wells?
Pulley in wells helps to pull the water because force is multiplied in movable pulley and in fixed pulley force is transfered from point to point.
Which compound machine consists of both fixed and moveable pulleys?
A compound machine that consists of both fixed and movable pulleys is a fixed pulley. This machine changes the direction of the force on a rope or belt that moves along its circumference.
What is the function of pulley?
Pulley reduces the force given to get the work done. There are amny types of pulleys. Examples are fixed pulley, movable pulley and Combined pulley.
How is IMA determined for pulleys?
IMA for pulleys is the resistance force divided by the effort force.
What type of pulley would increase the output force?
A pulley system that has multiple pulleys in line with each one having its output drive the next will increase the force. This would be called a tackle pulley.
How many times a force is multiplied by a machine is the machanical?
The mechanical advantage.
What is the advantage of a movable pulley?
a fixed pulley changes the direction you are executing the force in. fixed pulleys are made to work with gravity which makes the work you must use less than if you were lifting straight up and against gravity.
How can pulleys be used to reduce the force in lifting up an object?
They convert distance into force. So putting a pulley on a load would result in you having to haul up twice as much rope, but lifting about half of the weight of the load. Multiple pulleys increase rope length and further decrease force required to move the load.
What does a pulley do to the direction of a force?
Pulleys change the direction of a force.
How does a movable pulley effect force?
