Answer:
Design of Experiment also known as DoE is a systematic methodology to understand how any process or parameters of any product affects the response variables like physical properties or performance of any product, etc. It serves the purpose of making the job easier.
It is technique to generate valuable information required with minimum experimentation with the use of these:
- Statistical methodology
- Mathematical analysis to predict the output within the limits of experiments at any point.
- Experimental extremities
Process Optimization:
It includes the following:
- Product prototype should be used in designing
- Optimization of significant value adding activities
- Detection and minimization of error
- Strong built concept for the design
- Testing and validation of the process for further improvement in efficiency
- Time, quality, environmental, manufacting and overall cost, safety and operational constraints should be duly noted.
Answer:
0.234
Explanation:
True stress is ratio of instantaneous load acting on instantaneous cross-sectional area
σ = k × (ε)^n
σ = true stress
ε = true strain
k = strength coefficient
n = strain hardening exponent
ε = ( σ / k) ^1/n
take log of both side
log ε =
( log σ - log k)
n = ( log σ - log k) / log ε
n = (log 578 - log 860) / log 0.20 = 0.247
the new ε = ( 600 / 860)^( 1 / 0.247) = 0.234
Answer:
It makes its own light Im Sure its that one hope this helps you :)
Explanation:
It makes its own light then it gives us light if that makes sense...
Answer:
brake fade. loss of brake effectiveness due to overheating.
Explanation:
Acceleration of Car = 10 ms⁻²
Explanation:
Step 1:
The basic formula of acceleration is a = (v-u)/t ms⁻²
where, v- final velocity
u- initial velocity
t= time taken
Step 2:
Here v = 70 ms⁻¹
u = 50 ms⁻¹
t = 5 s
∴ a = ( 70 - 20)/5
a = 10 ms⁻²
