Answer:n=0.973
Explanation:
Given
When True strain
at
When True stress=346.2 MPa
true strain =0.226
We know
where =True stress
=true strain
n=strain hardening exponent
k=constant
Substituting value
Divide 1 & 2 to get
Taking Log both side
n=0.973
Answer:
The answer is below
Explanation:
Let A represent the first switch, B represent the second switch and C represent the bulb. Also, let 0 mean turned off and 1 mean turned on. Since when both switches are in the same position, the light is off. This can be represented by the following truth table:
A B C (output)
0 0 0
0 1 1
1 0 1
1 1 0
The logic circuit can be represented by:
C = A'B + AB'
The output (bulb) is on if the switches are at different positions; if the switches are at the same position, the output (bulb) is off. This is an XOR gate. The gate is represented in the diagram attached below.
Answer:
Explanation:
Given
velocity at A is
For
velocity is increasing at
Tangential acceleration is given by
at
thus
Velocity in terms of Displacement is given by
When car has traveled th of distance i.e.
on solving we get
Thus velocity at
(b)Acceleration when car has traveled three-fourth the way of track
normal acceleration
Tangential acceleration
Net acceleration
