How a car break works?
The break system of a car is composed by several items that are always working together to slow down and bring a vehicle to a complete stop. It also has the function of keeping the car stationary when it is parked. In general, this system has two manual activation modes: the lever and the pedal, with the exception of vehicles adapted for people with disabilities.
Most vehicles today use the disc brake system. Disc brakes work by using pads, which are held inside a hydraulic caliper, receiving pressure to brake. Such pads generate friction on a disc, which makes the vehicle stop permanently.
The drum brake is another type, being older and dependent on the famous linings to cause friction in the wheel and stop the vehicle. A hydraulic cylinder makes the plies move inside the drum, which is a hollow part fastened with screws and attached to the wheels. This type of brake is on the rear wheels, for the most common models.

The Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s. See the computation below.
What is travel speed?The travel speed of the welding flame or gun across the workpiece is simply measured in millimeters per minute.
Travel speed, along with voltage and amperage, is one of three factors in arc welding that affect the amount of heat input.
What is the calculation that justifies the above answer is?We are given the following:
Melting temperature = 1650 K
k = (3.33 * 10⁻⁶) * (1,650)²
k = 9.066 J/mm^3
The formula for velocity here is given as:

The displacement of a particle which moves along the s-axis is given by; = (−2 + 3)−0.5 Where s is in meters and t is in seconds. Determine the time at which the acceleration is zero.
The time at which the acceleration is zero is given as 4.66 seconds
How to solve for the timeFirst we have to solve for the velocity. To do this, we would have to take the derivative.
[tex]s = e^-0.5t (3 t - 2)[/tex]
Then velocity =
[tex]ds/dt = e^-0.5t (4 - 1.5 t)[/tex]
The acceleration can be gotten by finding the second derivative
[tex]a = dv/dt = e^-0.5t (.75 t - 3.5)[/tex]
To find t at acceleration = 0
We have
[tex]0 = e^-0.5t (.75t - 3.5)[/tex]
This gives t to be
t = 4.66 sec
Complete questionThe displacement of a particle which moves along the s-axis isgiven by

Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt.% at a position of 4 mm into an iron-carbon alloy that initially contains 0.10 wt.% C. The surface concentration is to be maintained at 0.90 wt.% C, and the treatment is to be conducted at C. Use the diffusion data for -Fe in Table 5.2
The carburizing time necessary to achieve a carbon concentration is 31.35 hours
How to find the Carburizing Time?To determine the carburizing time necessary to achieve the given carbon concentration, we will use the equation:
(Cs - Cx)/(Cs - C0) = ERF(x/2√Dt)
where;
Cs is Concentration of carbon at surface = 0.90
Cx is Concentration of carbon at distance x = 0.30
Distance x = 4 mm = 0.004 m
C0 is Initial concentration of carbon = 0.10
ERF() = Error function at the given value
D = Diffusion of Carbon into steel
t = Time necessary to achieve given carbon concentration ,
Thus, plugging in the relevant values gives;
(Cs - Cx)/(Cs - C0) = (0.9 - 0.3)/(0.9 - 0.1)
= 0.6/0.8 = 0.75
now, ERF(z) = 0.75 and as such using ERF table, we can say that;
Z = 0.814. Thus;
(x/2√Dt) = 0.81
Using the table of diffusion data, we have;
At a temperature of (1100°C) or 1373 K, we have;
D = 5.35 × 10⁻¹¹ m²/sec.
Calculating the carbonizing time by using the equation z = (x/2√Dt);
where;
t is carbonizing time
Thus;
0.814 = (0.004/(2 × √5.35 × 10⁻¹¹ × √t))
0.814 = 0.004 /(1.4628 × 10⁻⁵ × √t)
0.814 × 1.4628 × 10⁻⁵ × √t = 0.004
1.19072 × 10⁻⁵ × √t = 0.004
√t = 0.004/(1.19072 × 10⁻⁵)
√t = 335.93
t = 112848.96 seconds
Converting to hours gives;
t = 112848.96/3600
t = 31.35 hours
Therefore, the carburizing time necessary to achieve a carbon concentration is 31.35 hours
