The welding method that requires the operator to observe and only make corrections is automated.

Answer: E

Explanation

The process of welding is used to merge different metals with the help of heating them to welding temperature.

The metals coagulate at their end point and then coagulate with other metals to join together.

The welding can be done completely manually termed as manual welding.

It can be done with the help of machine where the maximum work will be done by the machine only termed as semiautomatic welding.

The machine and automatic welding is the one where the whole process of welding will be governed completely by the machine only.

The automated welding is the one where the operator has the job to start the welding machine and then to observe the occurrence of defects after welding.

Answer:

center left-turn lane

Explanation:

A <em>center left turn lane</em> will be marked as described. The arrows, if present, generally indicate that left turns are permitted from the lane with these markings.

If the double yellow lines are solid, they are considered to be a "barrier" and are not to be crossed.

It is appropriate to use the following yield or failure criterion for ductile materials (a) Maximum shear stress or Tresca crite

Nataly [62]

Answer:

(b)Distortion energy theory.

Explanation:

The best suitable theory for ductile material:

(1)Maximum shear stress theory (Guest and Tresca theory)

It theory state that applied maximum shear stress should be less or equal to its maximum shear strength.

(2)Maximum distortion energy theory(Von Mises henkey's theory)

It states that maximum shear train energy per unit volume at any point is equal to strain energy per unit volume under the state of uni axial stress condition.

But from these two Best theories ,suitable theory is distortion energy theory ,because it gives best suitable result for ductile material.

A cylindrical brass rod has a length of 5.00cm extending from a holder and a diameter of 4.50mm. Its Young's modulus is 98.0GPa.

Galina-37 [17]

Answer:

elongation of the brass rod is 0.01956 mm

Explanation:

given data

length = 5 cm = 50 mm

diameter = 4.50 mm

Young's modulus = 98.0 GPa

load = 610 N

to find out

what will be the elongation of the brass rod in mm

solution

we know here change in length formula that is express as

δ = $\frac{PL}{AE}$ ................1

here δ is change in length and P is applied load and A id cross section area and E is Young's modulus and L is length

so all value in equation 1

δ = $\frac{PL}{AE}$

δ = $\frac{610*50}{\frac{\pi}{4} * 4.50^2 * 98*10^3}$

δ = 0.01956 mm

so elongation of the brass rod is 0.01956 mm
