INTRODUCTION TO CNC - Practice Mode

1) What is the full form of CNC?
Correct Answer: Computer Numerical Control
Explanation:

Voltage, also known as electric potential difference, is the measure of the electric potential energy per unit charge in an electrical circuit. It is commonly measured in volts (V).

You can use Ohm's law to calculate voltage. Ohm's law states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance. It is represented by the equation:

V = I x R

where V is the voltage, I is the current and R is the resistance.

Given the values of resistance (R) and current (I), you can substitute them into Ohm's law equation to find the voltage.

In this case, given R = 250 Ohms and I = 0.44 Amperes V = I x R V = 0.44A x 250 Ohms V = 110 Volts (V)

So the voltage of the circuit is 110 Volts

2) Which year the numerical control of new era spaned automation?
Correct Answer: 1952
3) Which century, the fixed automatic mechanism introduction?
Correct Answer: 18th Century
Explanation:

The filament resistance of a bulb is the resistance of the thin wire inside the bulb that glows to produce light. You can calculate the filament resistance of a bulb by using Ohm's Law, which states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance.

Ohm's Law can be represented by the equation: V = I x R

Where V is the voltage, I is the current, and R is the resistance.

To calculate the filament resistance of a 6 volt bulb that draws a current of 0.5 Amps, you can use this formula: R = V/I

Given that the voltage (V) is 6 Volts and the current (I) is 0.5 Amperes R = 6 / 0.5 R = 12 Ohms

So, the filament resistance of the bulb is 12 Ohm

4) Which year along with CNC systems the commercial industrial robot was manufactured?
Correct Answer: 1961
Explanation:

A watt-hour (Wh) is a unit of energy, equal to the energy used by a power of one watt for one hour.

A watt-second (Ws) is a unit of energy, equal to the energy used by a power of one watt for one second.

To convert watt-hours to watt-seconds, we can use the following formula:

Watt-seconds (Ws) = Watt-hours (Wh) x 3600

So 1 watt-hour is equal to 3600 watt-seconds.

So if we have 1 watt-hour, it is equal to 1 x 3600 = 3600 watt-seconds

5) In Which country the automatically controlled factory was introduced before two centuries?
Correct Answer: In Europe
