Grinding a bore.

That depends on the load.

in older cars like a model a ford,

the carborator was gravity fed so perhaps .5 psi or zero uphill with a low tank

carborators and a fuel pump 5 psi is plenty to lift the gasoline 10 ' or so

with fuel injection about 100 psi is common

diesel can be about 1000psi fuel injected at TDC

In order to have your question answered, you would have to state which bar material. Young's Modulus is different and specific to the material to which it is applied. It will be different for steel than for iron or aluminum.

Dislocations move because the resolved shear stress (Schmidfactor) is sufficient high enough to activate the glide system in which the slip plane lies. (slip)

Screw-dislocations in fact are able to move from one slip plane to another parallel plane (burgers vector does not change!).

In a fcc lattice a $dislocation may change the (111) plane to (1 -1 1) plane due to local stresses. (cross slip)

Edge dislocations can change their planes too. It is a thermally activated process which is called climb (vacancy flux).

The Gaseous buildup inside of the internal combustion chamber would cause engine failure, the engine to blow, and explode litterally

Less weight, imagine how much that would weigh if it was solid.

Then the wheel would collapse.

Which would happen some time Before all the spokes had gone.

Weight significantly affects the flight of a glider by influencing its lift-to-drag ratio and overall performance. A heavier glider requires more lift to maintain altitude, which can lead to a steeper descent rate if not enough lift is generated. Increased weight can also reduce the glider's ability to soar effectively, as it may struggle to take advantage of rising air currents. Consequently, managing weight is crucial for optimizing a glider's efficiency and flight duration.

Coz poiseuille eq is for poiseuille flow, which is a laminar flow, not turbulent flow. And it also need to be a fully developed , pressure driven flow.

yes it is : )

Interference occurs when the addendum of the involute gear goes on the increased. When this occurs there is a increase in the toothspace and decrease in the teeth of the particular gear.

So with reduction in the toothspace there occurs a slipping in the involute gear.

Inorder to reduce that particular condition we have to avoid interference in gears.

The secant modulus is the total stress or strain on an object as described by a stress-strain graph. The tangent modulus is the marginal strain.

My apologies... I got it wrong... it is just the material continually in contact with the flow in a valve.

Thank you anyway...

There is a substantial increase in radius across the rotating blade rows of a centrifugal compressor, which is its primary distinguishing feature from the axial-flow compressors to get higher-pressure ratio.

Who says the compression ratio on a centrifugal is higher than that of a screw compressor? Unless I`m not properly understanding the question, these facts are true: a screw (axial) compressor is a positive displacement machine, meaning everything that goes into it will come out. There are no losses for re-expansion etc. A centrifugal compressor`s impeller is designed with a given amount of `lift` which is basically the difference between suction and discharge pressures or compression ratio. Exceeding the designed lift capability results in a surge where the gas momentarily goes backwards through the impeller until the excess lift condition is corrected.

Diesel engines have a far higher compression which allows the diesel fuel to explode without the use of a spark plug.

You can construct a NAND gate using relays. If the contacts are in series, it is an AND gate. If the contacts are in parallel, it is an OR gate. Depending on which contact you use, it is a NOT gate. Simply pick the right combination of contacts and the meaning of the signal, and you can consider it to be a NAND gate.

DAC Easy Accounting is an accounting package from Sage Software.

A split phase induction motor has two sets of coils and a centrifugal start switch. The start winding is in series with the start switch. The start winding provides a rotating magnetic field in one direction enabling the motor to start. The motor can be reversed by reversing the connections of either the start winding or the run winding but not both.

Volumetric strain of a deformed body is defined as the ratio of the change in volume of the body to the deformation to its original volume. If V is the original volum and dV the change in volume occurred due to the deformation, the volumetric strain ev induced is given by ev =dV/V

Consider a uniform rectangular bar of length l, breadth b and depth d as shown in figure. Its volume V is given by,

This means that volumetric strain of a deformed body is the sum of the linear strains in three mutually perpendicular directions.
