a welder performance qualification test on 1" (25.4mm) thick plate. what range of base metal is the welder qualified to weld? How many tension specimens will be tested? And how many side bends will be tested?

Answers

Answer 1

A welder's accomplishment qualification test on an excellent" (25.4mm) thick plate determines their requirement range.

What does passing qualify the welder for?

According to AWS D1.1 Structural Welding Code for Steel, passing this test qualifies them to bind base metals with thicknesses 'tween 0.5" (12.7mm) and 2" (50.8mm).

The qualification test requires two pressure specimens, that assess stiffness, and four side bend specimens, which judge ductility and healthiness.

A small block sits at one end of a flat board that is 4.00 m long. The coefficients of friction between the block and the board are μs = 0.550 and μk = 0.400. The end of the board where the block sits is slowly raised until the angle the board makes with the horizontal is α0 , and then the block starts to slide down the board.
Part A
If the angle is kept equal to α0 as the block slides, what is the speed of the block when it reaches the bottom of the board?

Answers

The speed of the block when it reaches the bottom of the board would be 3.19 m/s.

How to calculate the speed?

Let's start by finding the height of the board when the block starts to slide. The maximum angle α0 at which the block will remain stationary on the board is given by:

μs = tan(α0)

Solving for α0, we get:

α0 = tan^-1(μs) = tan^-1(0.550) = 29.59 degrees

The height of the board when the block starts to slide is given by:

h = 4.00 m sin(α0)

h = 4.00 m sin(29.59 degrees)

h = 2.09 m

Now let's find the work done by friction. The friction force is given by:

f= μk * N

where N is the normal force acting on the block. The normal force is equal in magnitude and opposite in direction to the component of the gravitational force acting perpendicular to the board, which is given by:

N = mg cos(α)

where m is the mass of the block, g is the acceleration due to gravity, and α is the angle of the board. The kinetic friction force does negative work, which is equal to:

Wf = -f * d

where d is the distance the block travels down the board. The work done by gravity is equal to the change in potential energy, which is given by:

Wg = mgh

where h is the height of the board. At the bottom of the board, all of the potential energy has been converted to kinetic energy, so we have:

1/2 * m * v^2 = mgh - f * d

Solving for v, we get:

v = sqrt(2gh - 2μk(N/m) * d)

We can now substitute the values we have found:

h = 2.09 m

μk = 0.400

N = mg cos(α0) = mg cos(29.59 degrees)

d = 4.00 m

Substituting these values and solving for v, we get:

v = sqrt(2gh - 2μk(N/m) * d)

v = sqrt(2 * 9.81 m/s^2 * 2.09 m - 2 * 0.400 * (m * g * cos(29.59 degrees)/m) * 4.00 m)

v = 3.19 m/s

Therefore, the speed of the block when it reaches the bottom of the board is 3.19 m/s.

It was an immense help to meI confess I rather applaud myself as I look back!that I saw my service so strongly and so simply. I was there to protect and defend the little creatures in the world the most bereaved and the most lovable, the appeal of whose helplessness had suddenly become only too explicit, a deep, constant ache of ones own committed heart. We were cut off, really, together; we were united in our danger. They had nothing but me, and Iwell, I had them. It was in short a magnificent chance. This chance presented itself to me in an image richly material. I was a screenI was to stand before them. The more I saw, the less they would. I began to watch them in a stifled suspense, a disguised excitement that might well, had it continued too long, have turned to something like madness. What saved me, as I now see, was that it turned to something else altogether. It didnt last as suspenseit was superseded by horrible proofs. Proofs, I say, yesfrom the moment I really took hold.This moment dated from an afternoon hour that I happened to spend in the grounds with the younger of my pupils alone. We had left Miles indoors, on the red cushion of a deep window seat; he had wished to finish a book, and I had been glad to encourage a purpose so laudable in a young man whose only defect was an occasional excess of the restless. His sister, on the contrary, had been alert to come out, and I strolled with her half an hour, seeking the shade, for the sun was still high and the day exceptionally warm. I was aware afresh, with her, as we went, of how, like her brother, she contrivedit was the charming thing in both childrento let me alone without appearing to drop me and to accompany me without appearing to surround.
