What kind of machine is a knife

Complex machines are also called compound machines. Two or more simple machines work together to form a complex machine. Compound machines can do more difficult jobs than simple machines alone. Examples of complex machines are bicycle, wheel barrow, crane, car jack, lawn mover etc. The six simple machines are the wedge, screw, lever, pulley, inclined plane and the wheel and axle.

They all make work easier and have few or no moving parts. Background Information. There are three ways simple machines make work easier: by increasing the distance through which force is applied, by changing the direction of applied force, or by multiplying force of speed of the energy applied. That makes the far tip of the knife the fulcrum. Therefore the load is between the fulcrum and effort.

This is a second class lever, analogous to a wheelbarrow. A fork is an example of a wedge this chops food to make smaller pieces this make works easier by cutting food into smaller pieces to make it easier to eat. There are six different simple machines.

They interact with those body parts, like muscle and the brain, and each body part does its job, like moving or thinking. It allows the body to sustain itself and perform its functions. Thus the body functions as a complex machine which utilizes the production process internally to sustain itself. Machines make work easier by increasing the amount of force that is applied, increasing the distance over which the force is applied, or changing the direction in which the force is applied.

Complex machines have advantages over simple machines. They often are provide a better solution than just a simple machine alone. It is a type of wedge. A knife is actually a compound machine as it is both a wedge the cutting edge and a lever as it is normally used in cutting things. Yes, it is one of the simple machine like knife, cooker, lighter etc. The cutting edge would be classified as a wedge and the handle would be classified as a lever, making it a complex machine.

A knife is a wedge. A knife is an example of the simple machines known as wedges. The answer to this question is relative. Compared to a knife- no. Compared to a jet airplane- yes. A wedge, more commonly known as a knife. Because it only has one thing working to make function, not three or more.

Example, say you have a car, that is NOT a simple machine bacause it has about a bazillion parts making it function. An airplane is not a simple machine. A lever is a simple machine. A wheel is a simple machine. Any machine that can be described by a mathematical formula is a simple machine.
