Two engineers are discussing the various merits of hydroelectricity. Engineer A says that tidal barrage systems can generate ele

ctricity when the tide goes both in and out. Engineer B states marine turbines can turn slowly because the force of water is greater than the force of air. Which engineer, if either, is correct? Only engineer A is correct Only engineer B is correct Neither engineer A nor engineer B are correct Both engineer A and engineer B are correct

aksik [14]

Answer:

Tmax=14.5MPa

Tmin=10.3MPa

Explanation:

T = 600 * 0.15 = 90N.m

T_max =\frac{T_c}{j}  = \frac{x}{y}  = \frac{90 \times 0.0175}{\frac{\pi}{2} \times (0.0175^4-0.0125^4)}

=14.5MPa

T_{min} =\frac{T_c}{j}  = \frac{x}{y}  = \frac{90 \times 0.0125}{\frac{\pi}{2} \times (0.0175^4-0.0125^4)}

=10.3MPa

Discuss in detail the following methods used to redistribute income and wealth in cash grants?​
aev [14]

Answer:

Redistribution of income and wealth is the transfer of income and wealth (including physical property) from some individuals to others through a social mechanism such as taxation, welfare, public services, land reform, monetary policies, confiscation, divorce or tort law.

-The term typically refers to redistribution on an economy-wide basis rather than between selected individuals.

Interpretations of the phrase vary, depending on personal perspectives, political ideologies and the selective use of statistics.

-It is frequently heard in politics, usually referring to perceived redistribution from those who have more to those who have less. Occasionally, however, it is used to describe laws or policies that cause opposite redistribution that shift monetary burdens from low-income earners to the wealthy.

-

The phrase is often coupled with the term class warfare, with high-income earners and the wealthy portrayed as victims of unfairness and discrimination.

-

Redistribution tax policy should not be confused with predistribution policies. "Predistribution" is the idea that the state should try to prevent inequalities from occurring in the first place rather than through the tax and benefits system once they have occurred. For example, a government predistribution policy might require employers to pay all employees a living wage, not just a minimum wage, as a "bottom-up" response to widespread income inequalities or high poverty rates.

Many alternate taxation proposals have been floated without the political will to alter the status quo. One example is the proposed "Buffett Rule", which is a hybrid taxation model composed of opposing systems, intended to minimize the favoritism of the special interest tax design.

andrey2020 [161]

Answer:

number of pulses produced =  162 pulses

Explanation:

give data

radius = 50 mm

encoder produces = 256 pulses per revolution

linear displacement = 200 mm

solution

first we consider here roll shaft encoder on the flat surface without any slipping

we get here now circumference that is

circumference = 2 π r .........1

circumference = 2 × π × 50

circumference = 314.16 mm

so now we get number of pulses produced

number of pulses produced = \frac{linear\ displacement}{circumference} × No of pulses per revolution .................2

number of pulses produced = \frac{200}{314.16} × 256

number of pulses produced =  162 pulses

What impact does modulus elasticity have on the structural behavior of a mechanical design?
devlian [24]

Answer with Explanation:

The modulus of elasticity has an profound effect on the mechanical design of any machine part as explained below:

1) Effect on the stiffness of the member: The ability of any member of a machine to resist any force depends on the stiffness of the member. For a member with large modulus of elasticity the stiffness is more and hence in cases when the member has to resist a direct load the member with more modulus of elasticity resists the force better.

2)Effect on the deflection of the member: The deflection caused by a force in a member is inversely proportional to the modulus of elasticity of the member thus in machine parts in which we need to resist the deflections caused by the load we can use materials with greater modulus of elasticity.

3) Effect to resistance of shear and torque: Modulus of rigidity of a material is found to be larger if the modulus of elasticity of the material is more hence for a material with larger modulus of elasticity  the resistance it offer's to shear forces and the torques is more.

While designing a machine element since the above factors are important to consider thus we conclude that modulus of elasticity has a profound impact on machine design.
