Answer:
4 times around
Explanation:
The total number of teeth involved will be the same for each gear. If the front gear is connected to the pedal and it goes around twice, then 2·24 = 48 teeth will have passed the reference point.
If the rear gear is attached to the wheel, and 48 teeth pass the reference point, then it will have made ...
(48 teeth)/(12 teeth/turn) = 4 turns
Answer:
It made information easily accessible and ensured individuals became more vast in subject topics of interest.
Explanation:
Information revolution is different and unique and it came with the advent of computers and the internet. A lot of information is stored there which is too large and complex for the human brain.This helped people to access information without much stress as informations about almost every subject is on the Internet.
Individuals can check the informations up and become more vast in interested topics.
Answer:
as soon as there is a design to improve
Explanation:
As a design engineer, I started on the "design improvement" step as soon as I had an initial conceptual design.
__
Then, I started that step again when my boss told me, "make it better."
_____
The more interesting question is, "when do you <em>stop</em> the design improvement step?" (Judging by the constant barrage of software updates, that answer is, "never.")
Answer:
The shear plane angle and shear strain are 28.21° and 2.155 respectively.
Explanation:
(a)
Orthogonal cutting is the cutting process in which cutting direction or cutting velocity is perpendicular to the cutting edge of the part surface.
Given:
Rake angle is 12°.
Chip thickness before cut is 0.32 mm.
Chip thickness is 0.65 mm.
Calculation:
Step1
Chip reduction ratio is calculated as follows:


r = 0.4923
Step2
Shear angle is calculated as follows:

Here,
is shear plane angle, r is chip reduction ratio and
is rake angle.
Substitute all the values in the above equation as follows:




Thus, the shear plane angle is 28.21°.
(b)
Step3
Shears train is calculated as follows:


.
Thus, the shear strain rate is 2.155.
Answer:
D
Explanation:
ensuring project end on time through carefully planning and organizing
