What is a specialised machine?
There are many examples of a specialised machine. One is the printer used by a computer user. A bacon slicer machine used by a butcher is another. Even a bicycle is a specialised machine that needs a rider to pedal the machine along. Generally, a specialised machine is designed to do one task.
What are the difference between the machines and mechanisms?
A simple machine performs a task using energy. Is does so in a fully automated fashion. A mechanism is mechanical, and often requires input from the user.
What are the sources of error in a bell crank lever experiment?
It must be ensured that the lever just touches the knob before completing the task or noting the readings 1. weight of spring balance and chain
What is the function of the lever?
A lever can rotate around the fixed point that is called a pivot. Levers are used to reduce the force need to do a particular task.
How do you measure major diameter of internal thread?
The major diameter is the diameter of the crest of the thread. Use a Vernier gage and mesure the diameter of the crest points of contact ( maximum external thread diameter). Unified National thread series defines the expected major diamter and tolerance. For internal threads ( nuts) the major diameter is the diameter of the roots of the thread.
How does the work done a machine compare to the work done by a machine?
The work done by a machine is the output energy provided by the machine in an intended task, while the work done on a machine is the input energy required to operate the machine. The work done by the machine should ideally be greater than the work done on the machine to ensure efficiency.
How many movements does a simple machine use?
A simple machine typically uses one movement to accomplish its intended task. Examples of simple machines include levers, pulleys, and inclined planes.
What is labour saving divice?
A domestic washing machine would be one example. It is a machine that can be used to do some task that originally had to be done by hand.
Which simple machine changes the direction of force needed to do a task without changing the size of the force needed?
A pulley is a simple machine that changes the direction of the force required to perform a task without changing the amount of force needed. By redirecting the force, pulleys make it easier to lift or move heavy objects.
Is a mailbox a simple machine?
No, a mailbox is not considered a simple machine because it does not have moving parts that work together to accomplish a task. Simple machines are typically defined as basic mechanical devices that make work easier, such as levers, pulleys, or inclined planes.
How did machines develop?
A machine is merely something that performs or assists in performing a task. The simplest examples of machines are levers, pulleys, and wedges, all of which have probably been around in some form or another since before recorded history. So, I suppose no one really knows how they developed.
What simple machine was created before the AM radio were used to accomplish a similar task?
crystal set
A device with few if any moving parts that makes it easier to do work is a?
A simple machine. Examples include levers, pulleys, and inclined planes, which can help reduce the amount of force needed to perform a task.
Is work done with a machine the same work without a machine?
Work done with a machine can make the task easier by reducing the amount of force or energy required. This means that the same amount of work can be achieved with less effort when using a machine compared to doing the work without one.
How do you define a machine?
A machine is a device that uses energy to perform a task or function by transforming inputs into outputs. Machines can range from simple tools like levers and pulleys to complex systems like computers and airplanes.
What is the first task to be undertaken when setting and operating a center lathe?
The first task of operating a center lathe is to clean the area around it, the machine itself, and oiling the beds. But if you are asking what the first task is when the preparation of the machine and workplace is done, drawing and material collected, chuck replaced if necessary, cutting tools selected and set up, then the first task on the machine itself would be to clamp the workpiece in the chuck.
What does work input mean?
Work input refers to the amount of energy or effort required to perform a task or operation. It is typically measured in terms of the force applied over a certain distance. Work input is an important concept in physics and engineering to quantify the work done by a system or machine.
