What are some examples of a pulley?
wagons it has to constas of a rope or belt
IN a real pulley system the work supplied must be?
In a real pulley system, the work supplied must overcome both the gravitational force acting on the load and the frictional forces present in the system. Due to these factors, the actual work output is always less than the work input, which means that some energy is lost as heat due to friction. Therefore, the efficiency of the pulley system is determined by how much of the input work is converted into useful work lifting the load. It's essential to account for these losses when calculating the mechanical advantage and effectiveness of the system.
How many simple machines does a crane have?
If it goes up just some, it could be considered a ramp, or inclined plane. Otherwise it is not any sort of simple machine. Good question though:)
When was the pulley invented?
The block and tackle (or pulley system) was brought to us by Archimedes (287BC - 212BC) in Greece, but neither Archimedes, nor any who wrote about him and his extraordinary work dated the invention.stupid answer
What pulley system creates just directional advantage?
Single fixed pulley
Is a crane a type of a pulley?
A crane is a movable pulley
Is crane a pully inclined plane or lever?
A crane is typically a combination of a pulley system and a lever. The pulley system helps to lift heavy loads by reducing the amount of force required, while the lever provides mechanical advantage for moving and positioning the load.
What is an example of a complex machine using a pulley and a screw?
An example of a complex machine using a pulley and a screw is a crane. The pulley system allows for the lifting of heavy loads, while the screw mechanism is used to control the height and position of the crane's arm. Together, they enable the crane to efficiently move and position objects with precision.
What things have a pulley?
crane
Which simple machine is used in lifting a load with crane?
A crane utilizes a combination of simple machines, but the primary one involved in lifting a load is the pulley. The pulley system allows the crane to lift heavy loads with relatively less effort by applying force over a distance.
What is the formula for the percent efficiency of a pulley?
The formula for the percent efficiency of a pulley is (output work/input work) x 100%. It compares the output work (work done by the pulley) to the input work (work done on the pulley) to determine how efficient the pulley system is in transferring energy.
Why did they call a pulley a pulley?
it was called a pulley because you could hang stuf on it and then you could pull it... a pulley could be a crane or esaltor.
Examples of a pulley system?
There are many examples of a pulley system such as a drawbridge in a castle or a set of rock climbing gear
What is an example of a compound pulley?
An example of a compound pulley system is a crane. This system involves multiple pulleys connected in multiple systems to provide mechanical advantage for lifting heavy loads. By distributing the weight across various pulleys and ropes, a compound pulley system makes it easier to lift heavy objects.
What is an example of a block and tackle pulley?
A block and tackle pulley system consists of one fixed pulley and one moving pulley working together to lift heavy loads with less effort. For example, a flagpole typically uses a block and tackle pulley system to raise and lower the flag.
How do you lift an elephant into a rail car?
Use a pulley (crane) .
How do roped elevators work?
pulley system, much like the cabled elevators work.
