Advantages:
- allowed steel to be produced without fuel
- using the impurities of the iron to create the necessary heat
- reduced the costs of steel production
Disadvantages:
- could convert only a pig iron low in phosphorus and sulfur
- these elements could have been removed by adding a basic flux such as lime, but the basic sl*g produced would have degraded the acidic refractory lining of Bessemer's converter.

Technician A says that the block deck is the surface to which the cylinder head attaches and can be slightly concave-shaped. Technician B says that core plugs are used to fill the holes in the block used for casting. Who is right
Answer:Both Technician A and Technician B are right.
Explanation: The cracks in an engine can be detected when the engines are thoroughly cleaned because the transmission vent is basically designed to vent hot air.
Also pressure testing can equally detect cracks easily. When you increase the pressure,you will notice leaks from the blocks or cylinder indicating a crack on them.

What is in a catalytic converter that makes it so expensive?.
Answer:
A catalytic converter is expensive because it needs rhodium to reduce smog levels. Rhodium, at its current value, is extremely expensive which makes using it in a catalytic converter expensive. To make up for their cost, manufacturers have to increase the price of the catalytic converter.

What is the maximum rating of the motor branch-circuit short-circuit and ground-fault protective device for a 7 1/2-horsepower, 208-volt, 3-phase squirrel-cage induction motor using time-delay fuses?.
The maximum rating of the motor branch-circuit short-circuit and ground-fault protective device for a 7 1/2-horsepower, 208-volt, 3-phase squirrel-cage induction motor using time-delay fuses is approximately 45 A.
To determine the maximum rating of the motor branch-circuit short-circuit and ground-fault protective device for a 7 1/2-horsepower, 208-volt, 3-phase squirrel-cage induction motor, we can use the National Electrical Code (NEC) guidelines.
Step 1: Calculate Full Load Current (FLA)
The full load current (FLA) of a motor can be calculated using the formula:
[tex]\mathrm{FLA = \frac{Horsepower \times 746}{\sqrt{3}\times voltages \times efficiency \times power factor } }[/tex]
Since efficiency and power factor are not given, we will assume typical values of 0.85 for efficiency and 0.85 for power factor.
Given:
Horsepower (HP) = 7.5 HP
Voltage = 208 V
Efficiency = 0.85
Power Factor = 0.85
Substitute these values into the formula:
[tex]\mathrm{FLA = \frac{7.5 \times 746}{\sqrt{3}\times 208 \times 0.85 \times 0.85 } }[/tex]
Step 2: Determine the Maximum Rating:-
According to NEC guidelines, the maximum rating of the protective device can be calculated by multiplying the FLA by a percentage that corresponds to the type of motor and the type of protective device.
For a squirrel-cage induction motor with time-delay fuses, the percentage is typically around 175%.
Maximum Rating = FLA × 175%
Maximum Rating = 25.76A × 1.75 ≈ 45.12A
Rounded to the nearest standard fuse size, the maximum rating of the protective device is 45 A.

A particle moving on a straight line has acceleration a = 5-3t, and its velocity is 7 at time t = 2. If s(t) is the distance from, the origin, find s(2)-S(1).
Given acceleration a = 5-3t, and its velocity is 7 at time t = 2, the value of s2 - s1 = 7
How to solve for the value of s2 - s1
We have
= [tex]\frac{dv}{dt} =v't = 5-3t\\\\\int\limits^a_b {v'(t)} \, dt[/tex]
[tex]= \int\limits^a_b {(5-3t)} \, dt[/tex]
[tex]5t - \frac{3t^2}{2} +c[/tex]
v2 = 5x2 - 3x2 + c
= 10-6+c
= 4+c
[tex]s(t) = \frac{5t^2}{2} -\frac{t^3}{2} +3t + c[/tex]
S2 - S1
[tex]=(5*\frac{4}{2} -\frac{8}{2} +3*2*c)-(\frac{5}{2} *1^2-\frac{1^2}{2} +3*1*c)[/tex]

True or False? In the CAC-A process, the airstream
should come from behind the electrode and
between the base metal and the electrode.
True, it should come from behind the electrode and
between the base metal and the electrode.
True is the correct answer.
The airstream should penetrate or come between the base metal and the electrode from the back during the CAC-A operation.
How does CAC-A process works-The molten metal will first travel a great distance due to the air blast. Front of the gouging operation should have metal deflection plates.The airstream should penetrate between the base metal and the electrode from the back during the CAC-A operation. All combustible materials should be removed from the work area. If not properly contained, the mass of molten metal extracted at high current levels, which is rather significant, will become a fire danger.The second element is the loud noise. A very loud noise happens when there are strong currents and strong air pressure. Arc cutters ought to use ear protection, ear muffs, or earplugs. The air carbon arc cutting procedure (CAC) is used to cut metal, gouge out damaged metal, remove outdated or subpar welds, prepare grooves for welding, and root gouge full penetration welds.When slightly ragged edges are acceptable, air carbon arc cutting is also employed.Metals are joined using it as well. Metals are cut using an oxygen-fuel gas in the technique known as "arc oxygen cutting." In this procedure, the metal is heated up by the oxygen's reaction with it, melting it.To know more click here-
