Answer:
The correct solution is "5.74%".
Explanation:
The given values are:
Gravity of aggregate,
Gravity of asphalt,
Asphalt concrete mixture,
We know that,
Now,
The theoretical specific gravity of mix,
⇒
By putting the values, we get
hence,
The percentage of voids will be:
⇒ %V =
=
=
= (%)
Answer:
Explanation:
The detailed analysis, with free body diagram and step by step calculations with appropriate substitution is as shown in the attached files.
Answer:
(a) 0.1509 mm
(b) 0.00525 mm
Explanation:
Stress, is given by
where F is force and A is area and area is given by
hence
where d is the diameter. Substituting 9970 N for F and 10mm=0.01 m for d hence
From the attached stress-strain diagram, the stress of 127 Mpa corresponds to strain of 0.0015 and since strain is given by
where
is the strain,
is elongation and l is original length and making elongation the subject
and substituting strain with 0.0015 and length l with 100.6 mm then
(b)
Lateral strain is given by
and substituting
for
where v is poisson ratio then
and making
the subject then
and substituting 0.35 for v, 0.0015 for strain and 10 mm for d
and the negative sign indicates decrease in diameter
