Unit of ultimate tensile strength
Ultimate tensile strength (U) is calculated using:
The units of force is N (Newton) and the unit of Area is m^2
So, we have:
or
<em>Hence: (c) is correct</em>
Answer:
a)
b)
Explanation:
Given that:
diameter d = 12 in
thickness t = 0.25 in
the radius = d/2 = 12 / 2 = 6 in
r/t = 6/0.25 = 24
24 > 10
Using the thin wall cylinder formula;
The valve A is opened and the flowing water has a pressure P of 200 psi.
So;
b)The valve A is closed and the water pressure P is 250 psi.
where P = 250 psi
