A developer is having a single-lane raceway constructed with a 180 km/h design speed. A curve on the raceway has a radius of 320
m, a central angle of 30 degrees, and PI stationing at 11 511.200. If the design coefficient of side friction is 0.20, determine the superelevation at the design speed (Hint: Consider normal component of the centripetal force). Also, compute the length of curve and stationing of the PC and PT.

b.
Explanation:
For computing the normality and molarity of the acid solution first we need to do the following calculations
The balanced reaction
= 0.27264 g
= 0.006816 mol
Now
Moles of needed is
= 0.003408 mol
= 0.333984 g
Now based on the above calculation
a. Normality of acid is
= 0.4544 N
b. And, the acid solution molarity is
= 0.00005112
=
We simply applied the above formulas
Answer:
The answer is below
Explanation:
Given that:
Diameter (D) = 0.03 mm = 0.00003 m, length (L) = 2.4 mm = 0.0024 m, longitudinal tensile strength , Fracture strength
a) The critical length () is given by:
The critical length (4.5 mm) is greater than the given length, hence th composite can be produced.
b) The volume fraction (Vf) is gotten from the formula:
