The maximum height that the water can rise above the jet is; 35 m

How to find the height pressure of water?

The formula for pressure here is;

P = P₀ + ρgh

where;

P₀ is the pressure at the fluid's surface.

ρ is the density of the fluid. (density of water = 1000 kg/m³)

g is the acceleration due to gravity = 10 m/s².

h is height of rise of fluid

Now, the pressure at water surface is zero because the pressure the atmosphere exerts on the water is equal to the pressure the water exerts on the atmosphere. Thus, P₀ = 0 Pa

We are given P = 350 kPa = 350000 Pa. Thus;

350000 = 0 + (1000 * 10 * h)

350000 = 10000h

h = 350000/10000

h = 35 meters

The Travel Speed at which the welding operation can be accomplished is given as 7.147mm/s. See the computation below.

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.

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:

V = f1 * f2 * Rh / (k*A)

V = 0.9 * 0.6 * 3000 / (9.066*25)

V = 7.147 mm/s

The Deflection due to Triangular load is 11q₀L⁴/120EI

The deflection due to the triangular load is usually given as:

σ₁ = 11q₀L⁴/120EI

Deflection due to reaction (R[tex]_{b}[/tex])(σ₂) =

R[tex]_{b}[/tex]L³/3EI

⇒ σ₁ = σ₂⇒ 11q₀L⁴/120EI

= R[tex]_{b}[/tex]L/3EI= R[tex]_{b}[/tex]

= 11q₀L/40

In terms of structural engineering, a beam or node moving from its initial location is referred to as deflection.

It occurs as a result of the loads and forces that are placed on the body.

Deflection, also known as displacement, can result from the weight of the body structure itself or from externally applied stresses.

A structure's deflection must be taken into account during design, and the consequences of not doing so can be disastrous.

Maximum absolute values of the shear = 28 KN

Maximum absolute values of bending moment = 5.7 KN.m

A) We can see the beam loaded in the first image attached.

For the shear diagram, let us calculate the shear from point load to point load.

From A to C, summing vertical to zero gives; ∑fy = 0: -20 - V = 0

V = -20 KN

From C to D, summing vertical to zero gives; ∑fy = 0: -20 + 48 - V = 0

V = 28 KN

From D to E, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - V = 0

V = 8 KN

From E to B, summing vertical to zero gives; ∑fy = 0: -20 + 48 - 20 - 20 - V = 0

V = -12 KN

For the bending moment diagram, let us calculate the bending moment from point load to point load.

At point A, the bending moment would be zero. Thus, M_A = 0 KN.m

At point C, taking moment about point C and equating to zero gives;

M_C = 0. Thus; 20(0.225) + M = 0

M = -4.5 KN.m

At point D, taking moment about point D and equating to zero gives;

M_D = 0. Thus; 20(0.525) - 48(0.3) + M = 0

M = 3.9 KN.m

At point E, taking moment about point E and equating to zero gives;

M_D = 0. Thus; 20(0.75) - 48(0.525) + 20(0.225) + M = 0

M = 5.7 KN.m

At point B, taking moment about point E and equating to zero gives;

M_E = 0. Thus; 20(1.05) - 48(0.825) + 20(0.525) + (20 * 0.3) + M = 0

M = 2.1 KN.m

Answer:

y-intercept = -2

Explanation:

The general structure of an equation in slope-intercept form is:

y = mx + b

In this formula, "m" represents the slope and "b" represents the y-intercept. Remember how the Point (-10, -6) contains one "x" value and one "y" value. Using these values in addition to the slope, you can plug them into the equation to find the y-intercept.

x = -10 (from point)

y = -6 (from point)

m = 2/5

y = mx + b                                            <----- Slope-intercept form

y = (2/5) x + b                                       <----- Plug 2/5 into "m"

-6 = (2/5)(-10) + b                                  <----- Plug in "x" and "y" values from point

-6 = -4 + b                                             <----- Multiply 2/5 and -10

-2 = b                                                    <----- Add 4 to both sides

Therefore, the value of the y-intercept is b = -2. The complete equation of the line is:

y = (2/5)x - 2

The higher level of acceleration should be used when accelerating on a short highway entry ramp.

Given data:

When accelerating on a short highway entry ramp, you should use a higher level of acceleration to safely merge with the traffic already on the highway. This is particularly important when the entry ramp is short, as you need to reach the speed of the highway traffic and find a suitable gap to merge into the flow.

Using a higher level of acceleration allows you to match the speed of the vehicles on the highway more quickly and efficiently, reducing the risk of causing disruptions or potential hazards. It's essential to accelerate smoothly and decisively to ensure a safe merge onto the highway.
