1. characteristics of pulley
A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim. Pulleys are used singly or in combination to transmit energy and motion. Pulleys with grooved rims are called sheaves.
ANSWERThe pulleyA pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim. Pulleys are used singly or in combination to transmit energy and motion. Pulleys with grooved rims are called sheaves. In belt drive, pulleys are affixed to shafts at their axes, and power is transmitted between the shafts by means of endless belts running over the pulleys.
#Carry on Learners#Brainly Everyday2. What are the characteristics of a pulley?
A pulley is a wheel with a groove along its edge, that holds a rope or cable. Usually, two or more pulleys are used together. When pulleys are used together in this way, they reduce the amount of force needed to lift a load. A crane uses pulleys to help it lift heavy loads. Pulleys are one of the six simple machines.
Explanation:
hope it's help to you
pulley is used to reduce the amount of force needed to lift a load. It basically consists of a grooved wheel mounted on an axle or shaft and a rope or belt that runs within the groove. The three different pulley parts are a wheel, an axle, and a rope.Sorry if this is wrong but this is all :)
3. Instruction: Using a Venn Diagram, compare the characteristics, and advantagesof using the three kinds of pulley.fixed pulleyblock and tackle pulley movable pulley
Answer:
FIXED PULLY
A fixed pulley is one in which the drum is secured to a single spot. While the force required to lift or move an object is no different than if you were lifting it by hand, the fixed pulley allows you to change the direction of the force needed.
MOVABLE PULLY
A movable pulley is one in which drum moves as you are moving the load. There is no change in the direction of force that you need to apply, but the load will "feel" lighter than it is.
BLOCK AND TACKLE PULLY
A block and tackle or only tackle is a system of two or more pulleys with a rope or cable threaded between them, usually used to lift heavy loads.

Answer:
pulley • wheel on an axle or shaft
wheel and axle • machine consisting of a wheel attached to a smaller axle
screw • sharp-pointed metal pin with a raised helical thread running around it
Explanation:
• designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. its uses is to lifting things, pulleys can be used singly or with many pulleys working together in order to transport people or things and its example is the elevator.
• these two parts rotate together in which a force is transferred from one to the other. its uses is for raising weights or water buckets from wells.
• used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.

6. 4. Identify the characteristics and uses of each type of simple machine.(Science)SIMPLE MACHINES ,CHARACTERISTICS , ,USESInclined Plane Lever Wedge Wheel and Axle Pulley Screw
Answer:
The wedge
A wedge is an object that tapers to a thin edge. Pushing the wedge in one direction creates a force in a sideways direction.
The wheel and axle
A wheel and axle is made up of a circular frame (the wheel) that revolves on a shaft or rod (the axle).
The pulley
A pulley is a wheel that carries a flexible rope, cord, cable, chain, or belt on its rim.
Inclined plane
Moving an object up an inclined plane requires less force than lifting it straight up, at a cost of an increase in the distance moved.
Lever
Lever characteristics. Long resistance arm: speed and range of movement.
The main differentiating characteristics of machine screws are: overall size, shape of head, slot type, length, material, and thread type.

Answer:
Pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taut cable or belt, or transfer of power between the shaft and cable or belt. In the case of a pulley supported by a frame or shell that does not transfer power to a shaft, but is used to guide the cable or exert a force, the supporting shell is called a block, and the pulley may be called a sheave.Explanation:

Answer:
1. Pulley - a wheel with a grooved rim around which a cord passes. It acts to change the direction of a force applied to the cord and is chiefly used (typically in combination) to raise heavy weights.
2. Wheel and Axle -a simple lifting machine consisting of a rope which unwinds from a wheel on to a cylindrical drum or shaft joined to the wheel to provide mechanical advantage.
3. Screw -a short, slender, sharp-pointed metal pin with a raised helical thread running around it and a slotted head, used to join things together by being rotated so that it pierces wood or other material and is held tightly in place.

20. what are the distinguishing characteristics of each simple machine?-LEVER-INCLINED PLANE-PULLEY-WEDGE-SCREW-WHEEL AND AXLE
Answer:
Wedge: A device that forces things apart.
Wheel and axle: Used to reduce friction.
Lever: Moves around a pivot point to increase or decrease mechanical advantage.
Inclined plane: Raises objects by moving up a slope.
Explanation:
yan lang alam ko
Answer:
LEVER — Levers are varied, but all have a few components. They all have an arm, a straight, relatively inflexible part, like the handle of an axe or the entire length of a see-saw, that needs to be unbreakable and relatively unbendable. They also have a fulcrum, or pivot point on which the lever rests and pivots.
INCLINED PLANE — a flat supporting surface tilted at an angle, with one end higher than the othe
PULLEY — A pulley which has sealed ball bearings, is very strong, has a moderate weight, is not too big, has a large sheave, has a large anchor and becket hole will typically be more expensive than a pulley that does not have these characteristics.
WEDGE — simple machine that consists of two inclined planes, giving it a thin end and thick end.
SCREW — screws are overall size, the shape of the head, slot type, length, material, and thread type.
WHEEL AND AXLE — The wheel and axle consists of a round disk, known as a wheel, with a rod through the centre of it, known as the axle. This system uses angular momentum and torque to do work on objects, typically against the force of gravity. The wheel and axle simple machine is closely related to gears.
