natali 33 [55]3 years ago
6 0

Answer:

Some of the irreversibilities are listed below:

  • Plastic deformation of solids
  • Transfer of heat over finite difference of temperature
  • When two fluids are mixed together the process is irreversible
  • Combustion of a gas
  • Current flowing through a finite resistor
  • Diffusion and free compression or expansion of gas
  • Relative motion of body with force of friction
  • Processes involving chemical reactions(spontaneous)

grigory [225]

There are different kinds of care given to machine parts. Technician A says that a pilot bearing should always be replaced when a clutch is replaced is a true statement and thus is the only correct one.

<h3>When should I replace my pilot bearing?</h3>
  • If one notice vibration on the clutch pedal, it is shows that it is worn-out bearing and thus needs changing.

Most times, pilot bearing is often replaced as kind of precautionary measure that is taken when clutch is replaced.

Torsional vibrations are said to be vibrations due to firing force twisting and accelerating of the crankshafts when a cylinder fires and cannot be absorbed by oft-dampened clutches.

Which type of engineering design uses an already existing design
Snezhnost [94]

Answer:

Reverse engineering

Explanation:

Reverse Engineering is the remaking of already made products following the deconstruction and examination of the product to make known the product design, code and architecture features, gain knowledge of the composition and construction in a scientific research approach

Reverse engineering is also known as back engineering and consists of three main stages

1) Recovery implementation

2) Design recovery

3) Recovery analysis.

Sergio [31]

Answer:

676 ft

Explanation:

Minimum sight distance, d_min

d_min = 1.47 * v_max * t_total where v_max is maximum velocity in mi/h, t_total is total time

v_max is given as 50 mi/h

t_total is sum of time for right-turn and adjustment time=8.5+0.7=9.2 seconds

Substituting these figures we obtain d_min=1.47*50*9.2=676.2 ft

For practical purposes, this distance is taken as 676 ft

A disk is rotating around an axis located at its center. The angular velocity is 0.6 rad/s and the angular acceleration is 0.3 r
zzz [600]

Answer:

a=0.0937 \ m/s^2

Explanation:

Given that

Angular velocity (ω)= 0.6 rad/s

Angular acceleration (α)= 0.3 rad/s^2

Radius (r)= 0.2 m

We know that is disc is rotating and having angular acceleration then it will have two acceleration .one is radial acceleration and other one is tangential acceleration.

So

Radial\ acceleration(a_r)=\omega ^2r\ m/s^2

Radial\ acceleration(a_r)=0.6^2 \times0.2 \ m/s^2

(a_r)=0.072 \ m/s^2

Tangential\ acceleration(a_t)=\alpha r\ m/s^2

Tangential\ acceleration(a_t)=0.3\times 0.2\ m/s^2

(a_t)=0.06 \ m/s^2

So the total acceleration ,a

a=\sqrt{a_t^2+a_r^2}\ m/s^2

a=\sqrt{0.06^2+0.072^2}\ m/s^2

a=0.0937 \ m/s^2
