Answer:

The correct answer is " $K_c=6.0369 \ MPa\sqrt{m}$ ".

Explanation:

Given:

Maximum load,

P = 50,000 N

Crack length,

a = 3mm

or,

= 3×10⁻³ m

Diameter,

d = 32 mm

As we know,

⇒ Maximum stress, $\sigma=\frac{P}{A}$

$=\frac{50000}{(\frac{\pi}{4}\times 32^2)}$

$=62.20 \ N/mm^2$

Now,

⇒ Fracture tougness, $K_c=Y \sigma\sqrt{\pi a}$

On substituting the values, we get

$=1\times 62.20\times \sqrt{3.14\times 3\times 10^{-3}}$

$=6.0369 \ MPa\sqrt{m}$

Answer:

Set point

Explanation:

PID control compares a measurement to a specified set point. The difference between those values is input into tuning parameters that send a signal to the process to make the correction.
