technician a says that cylinder components are the most highly stressed parts of the diesel engine. technician b says cylinder pressures can now exceed 3000 pounds per square inch (psi) (20,684 kilopascals [kpa]) of force. who is correct?
Only technician A is correct because cylinder components are the most highly stressed parts of the diesel engine but cylinder pressures can NOT exceed 3000 pounds per square inch (psi) at this time.
What are the facts that prove the above?The findings of the nonlinear static analysis revealed that the high-stress area was situated in the crack start zone while the engine was operating at maximum power.
Peak cylinder pressures near TDC (where spark occurs) will be in the 300 psi range for light load engines, 1000 psi for full-power production engines, and 1500 psi or higher for race engines.

which type of drawing commonly describes hydraulic and pneumatic circuits electrical power and fluid flow
The type of drawing commonly describes hydraulic and pneumatic circuits electrical power and fluid flow is fluid power.
The technologies of hydraulics and pneumatics are referred to as fluid power. Both systems transfer electricity from one place to another using a fluid (liquid or gas). In pneumatics, the fluid is a gas, whereas in hydraulics, the fluid power is typically a liquid (oil) (usually compressed air).
Both are methods of power transmission, which is the science of transforming energy into a form that is more usable and transferring it to the locations where it is required. Electrical, mechanical, and hydraulic power are the three most popular ways to transmit power.
Although they are occasionally seen as rival technologies, there is no one type of power transmission that is ideal for all uses. In actuality, a variety of technologies are used to suit the majority of applications. However, compared to other methods, fluid power has several significant advantages.

the hydraulic gradient is: group of answer choices the permeability of the rock. the slope of the water table. the increase in temperature with depth. the rate of flow of groundwater.
Groundwater moves in the direction of maximum decreasing total head under the influence of the hydraulic gradient.
Explain about the hydraulic gradient?The change in water level per unit of distance along the direction of highest head drop is known as the hydraulic gradient (1), which is the slope of the water table or potentiometric surface.
If the gradient is negative, which means the hydraulic head is lower at depth, there is an indication of a downward flow component. The hydraulic head is higher at depth if the gradient is positive, on the other hand, which denotes an upward flow component. The gradient's size tells us a lot about its importance.
This vector depicts the flow direction of groundwater, with zero denoting "no flow" and negative values denoting flow along a dimension.

assume the skin friction drag on the airfoil is essentially that for a flat plate with the boundary layer being laminar and incompressible. what percentage of the total drag is due to skin friction?
Preliminary studies found that skin friction drag accounts for between 20 to 40% of overall drag.
Explain about the skin friction?Aerodynamic drag, which is a resistive force applied to an object moving in a fluid, includes skin friction drag.
The viscosity of a fluid as it passes across a surface is what creates skin friction. Its size is determined by the fluid's viscosity, the amount of wetted (or total) surface area in contact with it, and the degree of roughness of the surface.
Skin friction is important because it plays a role in the erosion of sediment particles from the water-bed boundary condition. Regarding the vertical mixing of the sediment over the water depth, form drag-related turbulence (separation-induced eddies, etc.) is significant.

A homogeneous 800kg bar AB is supported at either end by a cable asshown in the figure
below. Calculate the smallest area of each cable if the stress is not to exceed 90MPa in bronze and
120MPa in steel.
The smallest area of each cable if the stress is not to exceed 90MPa in bronze is 43.6 mm² and 120MPa in steel is 32.7 mm².
What is normal stress?If the direction of deformation force is perpendicular to the cross-sectional area of the body, the stress is called normal stress. Changes in wire length and body volume will be normal.
σ = P/A
Where, σ = Normal stress
P = Pressure
A = Area
1 Kg = 9.81 N
800 kg = 7848 N
Since the rod is half bronze and half steel
800 kg = 7848/2
= 3924 N
Pₙ = Fₙ = 3924 N [n = Bronze]
Pₓ = 3924 N [x = steel]
Given,
σₙ = 90MPa
σₓ = 120MPa
Aₙ = ?
Aₓ = ?
Aₙ = Pₙ/σₙ
Aₙ = 3924/90
Aₙ = 43.6 mm²
Aₓ = Pₓ/σₓ

A auto transformer is any transformer in which the primary and secondary circuits have a portion of their two windings in common.
What is transformer?
A transformer is a passive part that moves electrical energy between circuits, whether they be single circuits or multiple circuits. The electromotive force (EMF) across any coils wound around the same core changes in response to changes in the current flowing through any one of the transformer's coils, which causes changes in the magnetic flux in the transformer's core. Without a metallic (conductive) connection between this same two circuits, electrical energy can be transferred between different coils. The 1831 discovery of Faraday's law of induction defines the induced voltage effect in any coil as the result of a fluctuating magnetic flux surrounding the coil.

High-angle grain boundaries that sweep the deformation substructure infrequently. After cold plastic deformation and/or during hot working, RECOVERY, RECRYSTALLIZATION, AND GRAIN GROWTH are microstructural changes that take place during annealing. Because they return the microstructural configuration to a lower energy level, these three mechanisms are commonly referred to as restoration processes. Recovery is crucial for removing internal stresses from forged, welded, and manufactured equipment without reducing the strength developed during and after use.

It is true that wt steel shape is produced by cutting a wide flange beam lengthwise in half.
A beam is a structural component that resists loads mostly applied laterally to its axis (an element designed to carry primarily axial load would be a strut or column). Its primary method of deflection is bending. Reaction forces are produced at the beam's support points as a result of the loads placed on it.
As a result of all the forces operating on the beam, internal stresses, strains, and deflections of the beam are caused by shear forces and bending moments within the beams. Beams differ from one another in terms of how they are supported, their profile (the form of their cross-section), equilibrium circumstances, length, and material.
