In a heat-treating process, a 1-kg metal part, initially at 1075 K, is quenched in a closed tank containing 100 kg of water, ini

tially at 295 K. There is negligible heat transfer between the contents of the tank and their surroundings. Modeling the metal part and water as incompressible with constant specific heats 0.5 kJ/kg K and 4.4 kJ/kg K, respectively, determine the final equilibrium temperature after quenching, in K.

Write an expression for the output voltage of an AC source that has an amplitude of 19 V and a frequency of 240 Hz. (Use the fol
Umnica [9.8K]

Answer:

Expression for output voltage =  V = Vo sin wt

Explanation:

Amplitude of output voltage = Vo = 19 V

Frequency = f = 240 Hz

Now we know that

Angular frequency = w = 2 π (1 / T) = 2  π 240 = 480 π Hz

Expression for output voltage =  V = Vo sin wt

Expression for output voltage =  V = 19 (sin 480 π) t

Is it a problem that the stress intensity factor, K, from Irwin's near-tip approximation approaches infinity as you get close to
valina [46]

Answer:

No it is not a problem

Explanation:

It is not a problem because the stress intensity factor K would approach infinity as you get close to a crack tip and the intensity factor would approach Zero as you get too far away from the crack tip and this is simply because a crack is a notch with zero tip radius .

and The application of stress intensity factor k in respect to present fatigue crack tip is termed " linear elastic fracture mechanics "
