ANSWER:

Simple machine, any of several devices with few or no moving parts that are used to modify motion and the magnitude of a force in order to perform work. They are the simplest mechanisms known that can use leverage (or mechanical advantage) to increase force. The simple machines are the inclined plane, lever, wedge, wheel and axle, pulley, and screw.

The inclined plane

An inclined plane consists of a sloping surface; it is used for raising heavy bodies. The plane offers a mechanical advantage in that the force required to move an object up the incline is less than the weight being raised (discounting friction). The steeper the slope, or incline, the more nearly the required force approaches the actual weight. Expressed mathematically, the force F required to move a block D up an inclined plane without friction is equal to its weight W times the sine of the angle the inclined plane makes with the horizontal (θ). The equation is F = W sin θ.

inclined plane

In this representation of an inclined plane, D represents a block to be moved up the plane, F represents the force required to move the block, and W represents the weight of the block. Expressed mathematically, and assuming the plane to be without friction, F = W sin θ.

Encyclopædia Britannica, Inc.

The principle of the inclined plane is used widely—for example, in ramps and switchback roads, where a small force acting for a distance along a slope can do a large amount of work.

Answer:

CHARACTERISTICS

1. Inclined plane, simple machine consisting of a sloping surface, used for raising heavy bodies. The force required to move an object up the incline is less than the weight being raised, discounting friction. The steeper the slope, or incline, the more nearly the required force approaches the actual weight.

2. Levers can be used to exert a large force over a small distance at one end by exerting only a small force(effort) over a greater distance at the other.

3. A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place.

4. 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.

5. A pulley is a type of simple machine that uses a wheel with a groove in it and a rope. The rope fits into the groove and one end of the rope goes around the load. You pull on the other end. The pulley helps you to move the load or change direction of the force.

6. A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside.

USES

1. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade.

2. Levers make work easier by using leverage which multiplies the force. When you use a lever, you move a smaller force a longer distance in order to lift a load a short distance. Examples of levers include a seesaw, pliers, crowbars, and tweezers.

3. A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place.

4. Wheel and axle, basic machine component for amplifying force. In its earliest form it was probably used for raising weights or water buckets from wells. Its principle of operation is demonstrated by the large and small gears attached to the same shaft, as shown at A in the illustration.

5. A pulley is a simple machine that consists of a rope and a grooved wheel. The rope fits into the groove in the wheel, and pulling on the rope turns the wheel. Pulleys are generally used to lift objects, especially heavy objects. The object lifted by a pulley is called the load.

6. A screw is a special kind of inclined plane. It's basically an inclined plane wrapped around a pole. Screws can be used to lift things or to hold them together. Examples of the screw simple machine include swivel chairs, jar lids, and, of course, screws.

25. How does the different simple machines work? Describe their characteristics. Machines Scissors Stairs Safety pins How does it work? Ex. Cut paper Characteristics Ex. Sharp edge Type of Simple Machine Ex. wedge1.doorknob2.screw3.stairs4.safetypins​

Answer:

1. Doorknob:

The doorknob is a type of simple machine known as a wheel and axle. It consists of a cylindrical-shaped knob (wheel) that is attached to a metal rod (axle) that goes through the door. The user can rotate the knob to turn the axle, which in turn operates the latch mechanism that locks or unlocks the door.

Characteristic: The doorknob is designed to make it easier for a person to open and close a door by using rotational force, which is more convenient and efficient than trying to push or pull the door directly.

2. Screw:

The screw is a type of simple machine that is often used to hold objects together or to move them from one place to another. It consists of a threaded metal shaft (known as the screw thread) that is wound around a cylinder-shaped rod (known as the screw shank).

Characteristic: The screw works by converting rotational motion into linear motion, allowing the user to apply a great amount of force over a small distance. The screw is also designed to hold objects securely in place, as the threaded shaft creates a tight grip when turned.

3. Stairs:

Stairs are a type of simple machine known as an inclined plane. They consist of a series of flat steps that are connected by sloping sections, which allows the user to ascend or descend at a gradual angle.

Characteristic: Stairs are designed to make it easier for people to climb or descend from one level to another by reducing the amount of force required to lift themselves vertically. The sloping sections of the stairs allow the user to exert less force over a longer distance, which reduces the amount of work required to climb or descend.

4. Safety pins:

Safety pins are a type of simple machine known as a lever. They consist of a long, thin metal rod with a spring-loaded mechanism on one end and a sharp, pointed tip on the other.

Characteristic: The safety pin works by using the lever principle to apply force to an object. When the user presses down on the spring-loaded mechanism, the sharp tip of the pin is forced through the object, holding it in place. The lever mechanism also allows the user to apply a great amount of force over a small distance, making it an effective tool for holding objects securely.
