Normal stress in CG is 13.58 Ksi
When the deforming force is applied to an item, it deforms. The object will generate an opposing force from within to revert to its previous dimensions and shape. This restoring force will be applied in the opposite direction and have the same magnitude as the deforming force.Stress is a term used to describe how much of this restorative force is produced per unit area of the material. When the path of the deforming force is perpendicular to the body's cross-sectional area, stress is said to be normal stress. If the wire's length or the body's volume changes, the stress level will remain normal.

The moments of inertia are ranked as follows, from smallest to largest is I₁ < I₂ < I₃.
Moment of inertia is a physical quantity that measures an object's resistance to rotational motion. It is defined as the sum of the products of the mass of each particle in a system and the square of its perpendicular distance from the axis of rotation.
The formula for moment of inertia is:
I = Σmr²
where I is the moment of inertia, m is the mass of each particle in the system, r is the perpendicular distance of each particle from the axis of rotation, and the symbol Σ indicates a summation over all particles in the system.
Moment of inertia plays a crucial role in rotational motion, just as mass plays a crucial role in linear motion. It determines how much torque is required to produce a certain amount of rotational acceleration, and how quickly an object will respond to an applied torque.
The moment of inertia of an object depends on its shape and the distribution of mass within that shape. Objects with more mass distributed farther from the axis of rotation will have a higher moment of inertia and will be more resistant to rotational motion.
Moment of inertia is an important concept in many areas of physics and engineering, such as the design of rotating machinery, the motion of planets and other celestial bodies, and the behavior of molecules in quantum mechanics.
Here in the question,
To rank the moments of inertia I₁, I₂, and I₃ about axes through the centers of the rods, we need to use the parallel axis theorem, which states that the moment of inertia about an axis parallel to an axis passing through the center of mass of the object is equal to the moment of inertia about the center of mass plus the product of the mass and the square of the distance between the two axes.
Let's denote the distances between the centers of mass and the rods as r₁, r₂, and r₃, respectively.
Then we have:
I₁ = I₁_cm + m(r₁ + R/2)^2
I₂ = I₂_cm + m(r₂ + 2R)^2
I₃ = I₃_cm + m(r₃ + R/2)^2
To rank the moments of inertia, we need to compare the values of (r + R/2)^2, (r + 2R)^2, and (r + R/2)^2 + R²/4 for each of the pairs of balls. We can see that the last term is the same for all pairs of balls, so we only need to compare the first two terms for each pair.
For pair 1, we have:
(r₁ + R/2)^2 < (r₂ + 2R)^2
since r₁ < r₂.
For pair 2, we have:
(r₂ + 2R)^2 < (r₃ + R/2)^2 + R²/4
since r₂ < r₃.
Therefore, the moments of inertia are ranked from smallest to greatest is I₁ < I₂ < I₃.

If Isabella measures the same side of a battery, the voltage reading should remain the same at 9 V.
The basic principle of electricityThis is because voltage is a measure of the potential difference between two points on an electrical circuit, and since Isabella is measuring the same point on the battery, no potential difference exists and the voltage reading should remain the same.This can be supported by Ohm's Law, which states that the voltage of a circuit is equal to the current multiplied by the resistance.Since Isabella is measuring the same point on the battery, the resistance and current are the same, meaning the voltage should remain the same.If Isabella measures the same side of the battery, the voltage will remain the same at 9 V.This is because the voltage of a battery is measured between the two terminals and a single terminal has a voltage of 0 V, so measuring one side will not change the overall voltage.Evidence for this can be found in the behavior of the voltmeter; when measuring the same side of the battery, the voltmeter should not display any change in the voltage reading.To learn more about Ohm's Law refer to:
