Purpose of this machine?

Asked by: Carlos Plummer

What is the purpose of the machine?

The basic purpose for which most simple machines are designed is to reduce the effort (force) required to perform a simple task. To achieve this, the force applied must act over a longer distance or period of time resulting in the same amount of work being performed by a smaller force.

What is the purpose of a machine shield?

Machine guarding is a safety feature on or around manufacturing or other engineering equipment consisting of a shield or device covering hazardous areas of a machine to prevent contact with body parts or to control hazards like chips or sparks from exiting the machine.

What are special purpose machine tools?

Special-purpose machine tools are designed to perform special machining operations, usually for production purposes. Examples include gear-cutting and gear-grinding machines, broaching machines, lapping and honing machines, and boring machines.

How does a machine make work easier?

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.

What is a machine answer?

A machine is a thing that is created by people to make work easier. It is a tool or invention which multiplies the effect of human effort. The machine produces a mechanical advantage.

What is this word machine?

noun. an apparatus consisting of interrelated parts with separate functions, used in the performance of some kind of work: a sewing machine. a mechanical apparatus or contrivance; mechanism. Mechanics. a device that transmits or modifies force or motion.

What is the purpose of machine guards quizlet?

Guards provide physical barriers that prevent access to danger areas. Safeguarding devices either prevent or detect operator contact with the point of operation or stop potentially hazardous machine motion if any part of an individual’s body is within the hazardous portion of the machine.

What is machine safety?

Machines can help improve production efficiency in the workplace. However, their moving parts, sharp edges, and hot surfaces can also cause serious workplace injuries such as crushed fingers or hands, amputations, burns, or blindness. Safeguards are essential to protect workers from injury.

What are the three main areas of a machine?

All machines consist of three fundamental areas: the point of operation, the power transmission device, and the operating controls.

Can you explain the three main important reasons why we use machines?

Three main important reasons why we use machines are : It makes our work easier and faster. 2.It makes our work perfectly. Machines are versatile.

How are simple machines used in everyday life?

Simple machines make tasks simpler by reducing the amount of effort it takes for humans to perform certain tasks. Levers, pulleys, and inclines all have one thing in common: they reduce the amount of energy it takes for human to move or lift objects.

Which is a result of using a machine?

Answer choices: The mechanical advantage makes the work output greater than the work input. The machine can put out force without having any force applied to it. A large force can be exerted through a long distance to have a small force exerted through a short distance.

Which statement best describes a machine?

Which statement best describes why a machine is useful? A machine can decrease either the input force or the input distance needed to do a given amount of work.

What is the efficiency of the machine?

The efficiency of any machine measures the degree to which friction and other factors reduce the actual work output of the machine from its theoretical maximum. A frictionless machine would have an efficiency of 100%. A machine with an efficiency of 20% has an output only one fifth of its theoretical output.

What is the mechanical advantage of the machine?

In machines that transmit only mechanical energy, the ratio of the force exerted by the machine to the force applied to the machine is known as mechanical advantage. Under mechanical advantage the distance the load will be moved will be only be a fraction of the distance through which the effort is applied.

What is efficiency of simple machine?

The efficiency of a simple machine is defined as the ratio of useful work done by a machine (output work) to the total work put into the machine (input work). For ideal or perfect machine, work output is equal to the work input. Ideal machines are those imaginary machines which are frictionless.

How can you make a machine more efficient?

Because all machines lose input work to friction, one way to improve the efficiency of a machine is by reducing friction. Oil is used to reduce friction between the moving parts of car engines. The use of oil makes engines more efficient.

What is mechanical advantage and efficiency?

Mechanical Advantage and Efficiency. Machine – a device with which you can do work in a way that is easier or more effective. A machine makes work easier by changing the amount of force you exert, the distance over which you exert your force, or the direction in which you exert your force.

What is velocity ratio?

Definition of velocity ratio

: the ratio of a distance through which any part of a machine moves to that which the driving part moves during the same time.

What kind of lever is the seesaw?

first-class lever

If the fulcrum is in the between the output force and input force as in the seesaw, it is a first-class lever. In a second-class lever, the output force is in between the fulcrum and the input force. An example of a second class lever is a wheelbarrow.

How are the input and output forces of the parts of a compound machine related?

Explanation: The mechanical advantage of a compound machine is the ratio of the output force exerted by the last machine in the series divided by the input force applied to the first machine.

What is a machine in science?

A machine is any mechanical or organic device that transmits or modifies energy to perform or assist in the performance of tasks.

What equation would you use to calculate the ideal mechanical advantage of a wheel and axle?

In the case of a wheel and axle, the ideal mechanical advantage can be calculated using the equation IMA=Rr I M A = R r where R is the radius of the wheel and r is the radius of the axle.

How does a crowbar used to remove the top of a box change the direction of the force?

How does a crowbar change the direction of force? It is a lever. Normally you would pull up to open the box. With a crowbar you are pushing down to open the box.

Which of the following is a comparison of a machine’s work output with the work input?

Mechanical efficiency is a comparison of a machine’s work output with the work input.

What simple machine is made up of two inclined planes?

A wedge

A wedge is a simple machine used to push two objects apart. A wedge is made up of two inclined planes. These planes meet and form a sharp edge. This edge can split things apart.
