Answer:

d. Neither A nor B

Explanation:

Mostly for exhaust bolts we use impact wrenches. Impact wrenches are very useful on flywheels because the crank shaft needs to be fixed from rotating. Also impact wrenches are useful on cars for loosening wheel nuts.  The wheels need not to be restrained or the brakes need not to be applied to fiz wheels in position.

Varvara68 [4.7K]

The question is not complete. We are supposed to find the average value of v_o.

Answer:

v_o,avg = 0.441V

Explanation:

Let t1 and t2 be the start and stop times of the output waveforms. Thus, from the diagram i attached, using similar triangles, we have;

3/(T/4) = 0.7/t1

So, 12/T = 0.7/t1

So, t1 = 0.7T/12

t1 = 0.0583 T

Also, from symmetry of triangles,

t2 = T/2 - t1

So, t2 = T/2 - 0.0583 T

t2 = 0.4417T

Average of voltage output is;

v_o,avg = (1/T) x Area under small triangle

v_o,avg = (1/T) x (3 - 0.7) x (T/4 - t1)

v_o,avg = (1/T) x (2.3) x (T/4 - 0.0583 T)

v_o,avg = (1/T) x 2.3 x 0.1917T

T will cancel out to give;

v_o,avg = 0.441V

What is the difference between erratic error and zero error​
Slav-nsk [51]

The negative mark is balanced by a positive mark on the set key scale while the jaws are closed.

It is common practice to shut the jaws or faces of the system before taking some reading to guarantee a zero reading. If not, please take care of the read. This read is referred to as "zero defect."

There are two forms of zero error:

zero-mistake positive; and

Non-null mistake.

In a reversing 2-high mill, a series of cold rolling process is used to reduce the thickness of a plate from 45mm down to 20mm.
podryga [215]

Answer:

Explanation:

Given

Initial Thickness=45 mm

Final thickness=20 mm

Roll diameter=600 mm

Radius(R)=300 mm

coefficient of friction between rolls and strip (\nu)=0.15

maximum draft(d_{max})=\nu ^2R

=0.15^2\times 300=6.75 mm

Minimum no of passes=\frac{45-20}{6.75}=3.70\approx 4

(b)draft per each pass

d=\frac{Initial\ Thickness-Final\ Thickness}{min.\ no.\ of\ passes}

d=\frac{45-20}{4}=6.25 mm

zhannawk [14.2K]

Answer:

Option A

Explanation:

As per the article "Time Travel Is A Fun Science Fiction Story But Could It Be Real?" the gravitational field is a representation of curving space and time. As the gravity becomes strong, the space-time get more curved and hence the time gets slower.

Hence, option A is correct
