Answer:
Test the working prototype
Explanation:
After the prototype is built, it is put through basic operational tests and purpose of applicability or performance test
The prototype is also laboratory tested to determine how reliable it is with tests performed to determine the modes of failure. Performance of tests are carried out by subjecting the prototype to stresses beyond its designed stress such as to discover failure modes
The system is however tested in isolation at this stage and the performance and risks of the prototype are quantified after the test, with improvement requirement outlined for modification of the design.
Answer:
10.007
Explanation:
Assuming we have to find out the compression ratio of the engine
Given information
Cubic capacity of the engine, V = 245 cc
Clearance volume, V_c = 27.2 cc
over square-ratio = 1.1
thus,
D/L = 1.1
where,
D is the bore
L is the stroke
Now,
Volume of the engine V =
plugging values we get
245 =
Solving we get D =7 cm
therefore, L= 7/1.1 =6.36 cm
Now,
the compression ratio is given as:
r =(V+V_c)/V_c
on substituting the values, we get
r = (245+27.2)/27.2 =10.007
Hence, Compression ratio = 10.007
Answer:
The correct option is A
Explanation:
Thermoplastics are polymers that can be recycled. They can be melted with heat and moulded into any shape which becomes hard when cooled. The heat applied to it in the process of recycling does not affect its chemical composition.
There are two main classes of thermoplastics; semi-crystalline and amorphous.
An amorphous thermoplastic has a disorderly arranged molecular structure which makes it difficult to have a definite melting temperature (Tm). However, a semi-crystalline thermoplastic has a well arranged molecular structure which makes it melt after a certain/definite amount of heat is absolved. Hence, the correct answer is A
Answer:
Production function
Explanation:
A production function is a method of determining the difference between what goes into and what comes out of output. The formula Q = f(K, L, P, H) determines how much output you can receive from a given number of inputs. Labor (L), or individual worker input, is one of the production elements.
