A front wheel drive vehicle with four wheel disc brakes is pulling to the left. Tech A says an external kink or internal restric
STALIN [3.7K]

Answer:

Tech A is correct.          

Explanation:

A front-wheel-drive pulling to the left can result from several factors. One of them is definitely a faulty break.

A correct diagnosis linking the problem to the brakes is when there is an internal restriction and the pull is constant to one side and gets worse when the brakes are applied.

To confirm this, one would need to lift the vehicle and rotate each wheel by hand to check for excessive friction.

So the restriction may be caused by:

  • brake calipers that are sticky to the drum
  • too much brake fluid in the brake master cylinder - this prevents the caliper pistons from retracting when the brakes are released
  • misadjusted drum brakes and or parking brakes.

Cheers

Explain the difference in the heat transfer modes of conduction and convection.
LiRa [457]

Explanation:

Conduction is the heat transfer through a stationary matter by the physical contact.  

For example, the heat transferred between electric burner of stove and bottom of pan is transferred by the process of conduction.

Convection is heat transfer by macroscopic movement of the fluid. The particles of the fluid carry the current within themselves.  

For example, the water is the pot is warmed overall by heat transferred by the process of convection.

What is Euler's equation?
igomit [66]

Answer:

e^{ix} = cosx + i sinx

Explanation:

In mathematics, Euler's formula is an equation in complex analysis, that gives a relationship between an exponential factor and the trigonometric functions.

The Euler equation is:

e^{ix} = cosx + i sinx

Here,

e - base of the natural logarithm

i - imaginary unit

x - argument given in radians

sin , cos - trigonometric functions sine and cosine respectively.
