Answer:
The right answer is "2.2099 m³".
Explanation:
Given:
Mass,
m = 5 kg
Temperature,
T = 35℃
or,
= 35 + 273
Pressure,
P = 200 kPa
Gas constant,
R = 0.2870 kj/kgK
By using the ideal gas equation,
The volume will be:
⇒
or,
⇒
By substituting the values, we get
Answer:
initial diameter of the sample is 2.95 mm
Explanation:
given data
yield load = 2100 N
maximum load = 3400 N
failure load = 2350 N
ultimate engineering stress = 497.4 MPa = 497 × N/m²
to find out
What was the initial diameter of the sample in mm
solution
we will apply here ultimate engineering stress formula that is express as
ultimate engineering stress = ...............1
here A is area and P max is maximum load applied
so area =
here d is initial diameter
so put all value in equation 1
497 × =
solve it we get d
d = 2.95 × m
so initial diameter of the sample is 2.95 mm
