What does the simple machines help us?

Answer 1

Simple machines are the most basic ways of making work easier or more efficient. There are 6 of them (if the different kinds of levers are considered the same simple machine): Inclined plane: Spreads out the work needed to move the object, so less is needed at once. Lever (first class): Changes direction of force applied. Load is on the opposite side of the fulcrum than the side that the force is applied on. Lever (second class): The load and force are on the same side of the fulcrum, with the force being applied further from the fulcrum. The work is easier, but the load isn't lifted as high. Lever (third class): Similar to second class levers, the load and force are on the same side as the fulcrum, but the force is closer to the fulcrum. The work is therefore harder, but the load is lifted more efficiently Wheel and axle: Just what it sounds like. The wheel is a simple, but brilliant tool that makes it so the inside and the outside make the same amount of rotations in the same amount of time, but move at different speeds. Turning the axle makes the outside of the wheel move fast, while turning the outside of the wheel makes turning the axle easy. Pulley: Made up of a wheel and a rope, the rope fitting on the groove of the wheel. This machine can either change the direction of the force, increase the efficiency of lifting a load, or make lifting the load easier. The more times the rope goes around a set of two wheels, the more efficient the pulley gets Screw: Changes the direction of force from around in a circle to down. The tool the "Screw" was named after this simple machine. Wedge: Also changes the direction of force from in one direction to out. This is used by scissors, axes, knives, or anything else that can cut.

Answer 2

Simple machines are used in everyday life. A TV remote could be classed as a simple machine because it makes it easier for one to change television channels. A calculator is classed as a simple machine because people use that to add multiple figures up instead of using paper and pencil. Simple machines are basically anything that is used in everyday life that makes a task easier to perform.

Answer 3

Simple machines make work easier. The six simple machines are the lever, wedge, screw, inclines, planes, wheel and axle, and pulley. They help us do many things. A pulley is a machine made up of a wheel and rope. Some examples of pulleys are flag poles, sail boats, and cranes. Pulleys let you move objects up and down.

A screw is an inclined plane wrapped around a rod. Some examples of a screw are clamps, spiral stair cases, and wrenches. Screws hold things together.

An inclined plane is a flat surface that is higher on one end. Some examples of an inclined plane are door stops, bike ramps, and slides. Inclined planes help us move things to low or higher places.

Answer 4

purpose of machine is to rduce human work.

efficiency=output/input

Answer 5

Simple machines are a lot of our force. And changing the direction of the force.

Answer 6

calculators make math much easier.

computers

cars

just think of any machine you use
