Answer:
(1). False, (2). True, (3). False, (4). False, (5). True.
Explanation:
The term ''contouring'' in this question does not have to do with makeup but it has to deal with the measurement of all surfaces in planes. It is a measurement in which the rough and the contours are being measured. So, let us check each questions again.
(1). In contouring, it is necessary to measure position and not velocity for feedback.
ANSWER : b =>False. IT IS NECESSARY TO MEASURE BOTH FOR FEEDBACK.
(2). In contouring during 2-axis NC machining, the two axes are moved at the same speed to achieve the desired contour.
ANSWER: a=> True.
(3). Job shop is another term for process layout.
ANSWER: b => False
JOB SHOP IS A FLEXIBLE PROCESS THAT IS BEING USED during manufacturing process and are meant for job Production. PROCESS LAYOUT is used in increasing Efficiency.
(4). Airplanes are normally produced using group technology or cellular layout.
ANSWER: b => False.
(5). In manufacturing, value-creating time is greater than takt time.
ANSWER: a => True.
Answer:
Explanation:
A smaller clearance volume means a higher compression. A higher compression means better thermal efficiency. However a compression ratio too high might be troublesome, as it can cause accidental ignition of the fuel-air mix. This is the reason why Otto cycle engines have lower compressions that Diesel engines. In a Diesel engine the mix ignites by compression instead of a spark.
Answer:

Explanation:
Given value:
In point a:
The value of 
In point b:
calculating heat leaves formula= 
In point c:
calculating Heat transfer rate formula
Answer:
SiC=169.26 Mpa
Partially stabilized zirconia=507.77 Mpa
Explanation:
<u>SiC
</u>
Stress intensity, K is given by
hence making 
the subject where is applied stress, Y is shape factor, a is crack length
substituting the given figures and assuming shape factor, Y of 1
<u>Stabilized zirconia
</u>
Stress intensity, K is given by
hence making the subject where is applied stress, Y is shape factor, a is crack length
substituting the given figures and assuming shape factor, Y of 1
