Consider film condensation on a vertical plate. Will the heat flux be higher at the top or at the bottom of the plate? Why?

Answer:

During film condensation on a vertical plate, heat flux at the top will be higher since the thickness of the film at the top, and thus its thermal resistance, is lower.

Keith_Richards [23]

The IRS and the U.S Department of the treasury declared that social security recipients are not required to file a simple tax return to receive stimulus payments under the CARES Act.

Explanation:

Due to the impact of corona virus problem, the CARES Act calls for stimulus payment to be sent to Americans based on their gross income.

The Social security recipients are not required to file a tax return and do not take action and they will receive the payments directly to their bank accounts.

The Automatic payments will begin by next week. The eligible taxpayers who filed tax returns for 2019  or 2018 and chose direct deposit for their refund will automatically receive a stimulus payment of  $1,200 for individuals or $2,400 for married couples and $500 for each qualifying child.

Why is transverse unequal length wishbone preferred to that of equal length?
Damm [24]

Answer:

It allows the wheels to move of the neutral position without the tires scrubbing

Explanation:

The double wishbone suspension is independent and it can be used in both the front wheels and it affords very good control of the outward or inward tilting of the front wheel and it keeps the wheels perpendicular to the road surface

However, when equal length parallel wishbone are installed, it gives rise to scrubbing of the tires as the wheels turn in the tracks

The development of unequal length non-parallel transverse or converging wishbones with A-arms suspension resolved the tire scrubbing effect on the wheels when moving out of the neutral position.

If a torque of M = 300 N⋅m is applied to the flywheel, determine the force that must be developed in the hydraulic cylinder CD t
Licemer1 [7]

Answer:

<em>866.1 N</em>

Explanation:

The torque on the flywheel = 300 N-m

The force from the hydraulic cylinder will generate a moment on CA about point A.

The part of this moment that will be at point B about A must be proportional to the torque on the cylinder which is 300 N-m

we know that moment = F x d

where F is the force, and

d is the perpendicular distance from the turning point = 1 m

Equating, we have

300 = F x 1

F = 300 N   this is the frictional force that stops the flywheel

From F = μN

where F is the frictional force

μ is the coefficient of static friction = 0.4

N is the normal force from the hydraulic cylinder

substituting, we have

300 = 0.4 x N

N = 300/0.4 = 750 N

This normal force calculated is perpendicular to CA. This actual force, is at 30° from the horizontal. To get the force from the hydraulic cylinder R, we use the relationship

N = R sin (90 - 30)

750 = R sin 60°

750 = 0.866R

R = 750/0.866 = <em>866.1 N</em>
