Answer:
Part 1
4 mm⁴
Part 2
32 cm³
Explanation:
Part 1
The diameter of the circular cross section, d = 3 mm
The area moment of inertia of a circle, [tex]I_C[/tex], is given as follows;
[tex]I_x = I_y = \dfrac{\pi \cdot d^4 }{64}[/tex]
Where;
d = The diameter of the circle
Therefore, the area moment of inertia of the given circular cross section, with d = 3 mm, is found as follows;
[tex]I_x = I_y = \dfrac{\pi \times (3 \, mm)^4 }{64} \approx 4 \, mm^4[/tex]
Part 2
The minimum area moment of inertia for a rectangular cross-section is given as follows;
[tex]I_x = \dfrac{1}{12} \cdot b \cdot h^3[/tex]
[tex]I_y = \dfrac{1}{12} \cdot h \cdot b^3[/tex]
The minimum moment of inertia, for the rectangular cross-section is given by placing, the height, h = The short side length and calculating for, Iₓ, and vice versa
Therefore, for the question, where, h = 4 cm, and b = 6 cm, we have;
[tex]I_x = \dfrac{1}{12} \times 6 \, cm \times (4 \, cm)^3 = 32 \, cm^4[/tex]
Question 10: What is a K-turn?
Answer:
The three-point turn (sometimes called a Y-turn, K-turn, or broken U-turn) is the standard method of turning a vehicle around to face the opposite direction in a limited space, using forward and reverse gears. This is typically done when the road is too narrow for a U-turn.
When selecting the appropriate gear for intended direction of travel, automatic transmission equipped vehicles should be placed in _______ while manual transmission equipped vehicles should be placed in ______. a) Drive, first gear b) First gear, second gear c) First gear, drive d) Second gear, first gear
Answer:
Automatic transmissions should be in Drive and Manual transmissions should be in first gear.

find the first principle derivative for 3/x with respect to x.
Answer:
-3/x^2
Explanation:
Deriving is a lot like taking one away from the exponent. With that in mind, lets rewrite 3/x into 3x^-1. All we need to do is bring down the negative one then subtract one from the exponent. This gives us -3x^-2. We can convert it back to -3/x^2 .
