Give examples of complex machines and simple machines?
Well complex machines are usually hard to assemble and some times electronic like an xbox a microwave ect. A simple machine are usually made up of gears and wires like a clothes line a yo-yo ect. hope this helps
What are the simple machines in a camera?
A visible-light based microscope is basically a series of lances, each multiply the size of the image, let's say tenfold. The resulting image is 1,000 or 10,000 times bigger then reality.
What does the simple machines help us?
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.
Do simple machines reduce the amount of work?
By simple machines, I assume you mean machines powered by muscle but using leverage such as levers, screws, block and tackle devices. Is that what you mean? If so, these devices increase something called "mechanical advantage". Start with levers. The usefulness of a lever depends on where the fulcrum is placed. If the fulcrum is in the centre of a lever such as with a see-saw, there is no mechanical advantage at either end. That's why kids of similar weights can suspend the kid on the other end of the see-saw up in the air just to be rascals. Now if the fulcrum is closer to one end than to the other, the person farther from the fulcrum can exert more force than the person closer to the fulcrum. Think of a crow bar. One inserts an inch or two of the bar at the point where one wants to apply force. Pushing on the other end of the bar (perhaps two, three, four feet away) exerts a lot of force at the other end. The same effect allows you to lift a car with a jack. You push down a foot on the jack handle and the jack platform rises perhaps half an inch.
Who invented the 6 simple machines?
1. The Pulley- Probably the earliest lifting pulleys used a rope over tree branch to lift heavy objects. Although pulleys were in use around the time the pyramids were built there is no record of them being used in their construction.The first pulley systems built for lifting would have been made of tree trunks or branches with the rope over the horizontal part of the system. The use of wheels was the next step in the history of lifting pulleysAs people needed to transport goods over longer distances they discovered sails that used the power of the wind. To be able to use the wind power the sailors had to be able to raise and lower the sails. Pulleys were ideal for this task.About 1100 AD the building of large churches called cathedrals became popular. These buildings were very large and some were around 150 meters high. Huge blocks of stone had to be lifted to build the walls and spires. The cathedral builders were the same people who designed and built the pulley systems to lift the blocks of stone.2.The lever- Levers are one of the basic tools; they were probably used in prehistoric times. Levers were first described about 260 BC by the ancient Greek mathematician Archimedes (287-212 BC). Many of our basic tools use levers, including scissors, pliers, hammer claws, nutcrackers, and tongs.3.The Wedge- History is not clear since it has been around for around 9,000 years. Almost all known ancient civilations had their version of the wedge.4.The Wheel and Axle- The wheel is probably the single most important invention of all time. The oldest wheel was found in a place that is now called Mesopotamia. It is believed to be over fifty-five hundred years old. Before that time, people did not have wheels to move heavy objects. Axles were used to unite two or more wheels in order to achieve more work or transportation done.5.The Inclined Plane- The inclined plane is one of the simple machines of antiquity, the physical operations of which were first theorized by Archimedes in the second century B.C., and then further explained by Hero of Alexandria in the first century A.D.6.The Screw- Around the first century, screw shaped tools became common, however, historians do not know who invented the first. Early screws were made from wood and were used in wine presses, olive oil presses, and for pressing clothes. Metal screws and nuts used to fasten two objects together first appeared in the fifteenth century.
Is there always a benefit with simple machines?
There isn't always a benefit to simple machines sometimes they are easier other times they need to perform hard tasks and the simple machines cant do it

What were wages in the Bible times?
Wages paid to workers in Biblical times were exactly the same as wages paid worldwide today: some workers were paid in local currency (money), while others were paid 'in kind', that is, their work was rewarded with goods, services and other entitlements. As today, many workers received a mix of money and 'in kind' payments.
