Generally the equation for The Process is mathematically given by
Assuming Mass to be Equal
Where
Therefore
Answer:
0.05%
Explanation:
From the question, we have;
The yield strength of the mild steel, = 43.5 ksi
Young's modulus of elasticity, ∈ = 29,000 ksi
The total strain, = 0.2% = 0.002
The inelatic strain is given as follows;
=
-
/∈
Therefore, we have;
= 0.002 - 43.5/(29,000) = 0.0005
Therefore, the inelastic strain, = 0.0005 = 0.05%
Taking the inelastic strain as the residual strain, we have;
The residual strain = 0.05%
<h3><u>The velocity of the car after 10 s is 78.95 km/hr</u></h3>
Explanation:
<h2>Given:</h2>m = 1,250 kg
= 30 km/hr
F = 1,700 N
t = 10 s
<h2>Required:</h2>Final velocity
<h2>Equation:</h2><h3>Force</h3>F = ma
where: F - force
m - mass
a - acceleration
<h3>Acceleration</h3>a =
where: a - acceleration
- initial velocity
- final velocity
t - time elapsed
<h2>Solution:</h2><h3>Solve for acceleration using the formula for force</h3>F = ma
Substitute the value of F and m
(1700 N) = (1250 kg)(a)
a =
a = 1.36 m/s²
<h3>Solve for final velocity using the formula for acceleration</h3>- Convert 30 km/hr to m/s
=
=
- Substitute the value of a,
and t
a =
- Convert to km/hr
=
=
