The system includes a disk rotating on a frictionless axle and a bit of clay transferring towards it, as proven withinside the determine above.
<h3>What is the
angular momentum?</h3>
The angular momentum of the device earlier than and after the clay sticks can be the same.
Conservation of angular momentum the precept of conservation of angular momentum states that the whole angular momentum is usually conserved.
- Li = Lf where;
- li is the preliminary second of inertia
- If is the very last second of inertia
- wi is the preliminary angular velocity
- wf is the very last angular velocity
- Li is the preliminary angular momentum
- Lf is the very last angular momentum
Thus, the angular momentum of the device earlier than and after the clay sticks can be the same.

Explanation:
As a general rule of thumb, the large the diameter of a bearing, bushing or pin, the larger the tolerance range,” Brieschke points out. “The inverse is true for smaller-diameter pieces.”
Mike Brieschke, vice president of sales at Aries Engineering, says a 0.25-inch-diameter metal dowel that is press-fit into a mild steel hole usually has an interference of ±0.0015 inch. Parts in noncritical assemblies tend to have looser tolerances

Answer:
True
Explanation:
liquids are fluid, able to flow and take any shape. this occurs due to the weak intermolecular bonding that allows the molecules to slide past each other freely. as a result of being fluid, liquids exhibit many interesting properties that solids do not, including capillary action and diffusion. liquids, like gases, undergo diffusion when mixed.
Answer:
The term for the pole placement controller is G/(s² + 1) +GH
Explanation:
Solution
Given that:
A plant of order = 50
The sinusoids of frequency ω = 1 rad/sec.
Lt the transfer of equation of plant be represented as follows:
T/F = G/1+GH
= K/ans^50 + ans - 1^49 +........As +a₀
The pole placement order becomes:
Step 1:
Gc (s) =A/s
Now
The transfer function = GGc/1 +GG c H
=G/s + GHA
Step 2:
For sinusoidal controller w = = 1 rad/sec.
Gc (s) = w/s² + w²
= 1 + /s² + 1
Thus
The transfer function = GGc/1 +GGcH
= G/(s² + 1) +GH
the term for the pole placement controller is G/(s² + 1) +GH
