A rotating beam is subject to an alternating stress of 48 kpsi and a mean stress of 24 kpsi. The ultimate strength of the materi

Alisiya [41]

Answer:

goodman = 0.694

life of beam = 211597

Explanation:

alternating stress = 48 kpsi

mean stress = 24 kpsi

ultimate strength = 100 kpsi

endurance limit = 40 kpsi

goodman:

= $\frac{mean stress}{ultimate stress} +\frac{alternating stress}{endurance limit} =\frac{1}{N}$

= $\frac{24}{100} +\frac{48}{40} =\frac{1}{N}$

= 0.24 + 1.2 = $\frac{1}{N}$

N = 1/1.44

N = 0.694

2. check attachment for diagram

Log(N)-3/3 = log90 - log48/log90 - log40

Log(N)-3/3 = 0.77517

Log N = 5.325509

N = 10^(5.325509)

N = 211597

Advocates of small government complain that two proposed government programs will steal the market from small businesses: One pr

VashaNatasha [74]

Answer:

Explanation:

If the demand elasticity of bread is highly inelastic, it means the effect of change in price on demand of bread will be insignificant. Hence if a program fosters major increase in government production of bread, the prices of bread may get down. As law of demand states with lower price demand will be higher of government made bread. But as the demand is inelastic, there will be no significant effect on demand of bread of small business producing bread.

On other hand, If the demand elasticity of manicure is highly elastic, it means the effect of change in price on demand of manicure will be significant. Hence if a program that will increase in government production of manicures, the prices may get low. With lower price demand will be higher of government made manicure. And as the demand is highly elastic, there will be severe significant effect on demand of manicure of small business producing manicure.

Thus the second program worries small government proponents the most.

A heavy-duty electrical resistor is 2cm in diameter by 16cm long. 5 amps of current through it heats the resistor to 100°C, and

Olenka [21]

Answer:

The convective coefficient is 37.3 W/m²K.

Explanation:

Use Newton’s law of cooling to determine the heat transfer coefficient. Assume there is no heat transfer from the ends of electric resistor. Heat is transferred from the resistor curved surface.

Step1

Given:

Diameter of the resistor is 2 cm.

Length of the resistor is 16 cm.

Current is 5 amp.

Voltage is 6 volts.

Resistor temperature is 100°C.

Room air temperature is 20°C.

Step2

Electric power from the resistor is transferred to heat and this heat is transferred to the environment by means of convection.

Power of resistor is calculated as follows:

P=VI
