A slight breeze is blowing over the hot tub above and yields a heat transfer coefficient h of 20 W/m2 -K. The air temperature is
patriot [66]

Answer:4050 W

Explanation:

Given

Heat transfer Coefficient(h)=20 W/m^2-K

Air temperature =75 F

surface area(A)=7.5 m^2

Temperature of hot tube is 102 F

We know heat transfer due to convection is given by

Q=hA\left ( \Delta T\right )

Q=20\times 7.5\left ( 102-75\right )=4050 W

A strain gauge with a 5 mm gauge length gives a displacement reading of 1.25 um. Calculate the stress value given by this displa
KengaRu [80]

Answer:

stress  = 50MPa

Explanation:

given data:

Length of strain guage is 5mm

displacement\delta = 1.25 \mu m =\frac{1.25}{1000} =  0.00125 mm

stress due to displacement in structural steel can be determined by using following relation

E =\frac{stress}{strain}

stress = E \times strain

where E is young's modulus of elasticity

E for steel is 200 GPa

stress = 200\times 10^3 *\frac{1.25*10^{-3}}{5}

stress  = 50MPa

From the following numbered list of characteristics, decide which pertain to (a) precipitation hardening, and which are displaye
Blababa [14]

Answer:

(a) Precipitation hardening

(1) The strengthening mechanism involves the hindering of dislocation motion by precipitates/particles.

(2) The hardening/strengthening effect is not retained at elevated temperatures for this process.

(4) The strength is developed by a heat treatment.  

(b) Dispersion strengthening

(1) The strengthening mechanism involves the hindering of dislocation motion by precipitates/particles.  

(3) The hardening/strengthening effect is retained at elevated temperatures for this process.

(5) The strength is developed without a heat treatment.
