Pan Balance Activity
The goal of this activity is to develop an understanding of how to use manipulatives to support student development of the concept of equivalence - an important foundation for algebraic thinking. After you have explored the three pan balance activities, add a screenshot of your work from each activity in the space provided.
Pan Balance - Shape
Pan Balance - Numbers
Pan Balance - Expressions
RESPOND: Answer the reflective questions below.
1.
As you worked through the activities, what did you notice about the progression of skill as it related to each activity?
As I worked through each of the activities, I noticed that the progression of skill increased when I implemented greater values or more variables into the expressions. For instance, when
I was working through the shapes, I was able to determine the weight of each quickly. However, I would put more shapes on one side of the scale and less on the other just to prove that a singular shape weighed the same amount as multiple shapes. When I was working through the numbers, I found that adding more numbers or variables made the problem more advanced and required more skill to make the equations equal.
2.
How would you incorporate these activities into your classroom? In what part of the lesson sequence would using these types of representations be most appropriate?
In my classroom, I would incorporate these strategies by using the number strategy. I will have
my students create different number variations and equations equal. They will make them equal by using addition, subtraction, multiplication, and division. Using these types of representations will be most appropriate after learning the types of equations and where/when to use them. I would use these strategies as more of a review for my students before they take a quiz or test. Not only will it review their knowledge, it will also test them and allow them to progress their skills and abilities to solve different problems.

This is an engineering problem and not a writing assignment. Please Do Not Reject. I had other engineering tutors on bartleby help me with problems similar to this one.
This problem must be presented in a logical order showing the necessary steps used to arrive at an answer. Each homework problem should have the following items unless otherwise stated in the problem:
a. Known: State briefly what is known about the problem.
b. Schematic: Draw a schematic of the physical system or control volume.
c. Assumptions: List all necessary assumptions used to complete the problem.
d. Properties: Identify the source of property values not given to you in the problem. Most sources will be from a table in the textbook (i.e. Table A-4).
e. Find: State what must be found.
f. Analysis: Start your analysis with any necessary equations. Develop your analysis as completely as possible before inserting values and performing the calculations. Draw a box around your answers and include units and follow an…

Problem Description (CCOs #1, 2, 3, 4, 5, 6, 7, 8, 11, 12)
A water tank of radius R = 1.8m with two outlet pipes of radius r₁ = 0.05m and r2 installed at heights h₁ = 0.13m
and h₂ = 1m, is mounted in an elevator moving up and down causing a time dependent acceleration g(t) that must be
modeled as
g(t) = go+a1 cos(2π f₁t) + b₁ sin(2π f₁t) + a2 cos(2π f₂t) + b₂ sin(2π f₂t),

This example, extracted from a mock paper assigned by my lecturer for engineering maths revision, has proven to be quite the formidable challenge. It feels as though I've weathered through countless seasons grappling with it, yet progress remains elusive. Despite my earnest efforts, my search for pertinent information has yielded scant results. Might you be the gallant figure I need, summoned to rescue me from this academic labyrinth?

Learning Goal:
To describe the shape and behavior of cables that are subjected to concentrated and
distributed loads.
Part A
Structures often use flexible cables to support members and to transmit loads between
structural members. Because a cable's weight is often significantly smaller than the
load it supports, a cable's weight is considered negligible and, therefore, not used in
the analysis.
In this tutorial, cables are assumed to be perfectly flexible and inextensible. Thus, once
the load is applied the geometry of the cable remains fixed and the cable segment can
be treated as a rigid body.
Cables of negligible weight support the loading shown. (Figure 1) If W, = 85.0 N , W, = 510 N, YB = 1.40 m, yc = 2.80 m, yp = 0.700 m, and zc = 0.850 m, find zg.
Express your answer numerically in meters to three significant figures.

Learning Goal:
To be able to find the center of gravity, the center of
mass, and the centroid of a composite body.
Part A
A centroid is an object's geometric center. For an object
of uniform composition, its centroid is also its center of
mass. Often the centroid of a complex composite body is
found by, first, cutting the bodyng the weighted average

segments, and then by calculating i
of the segments' centroids.An object is made from a
uniform piece of sheet metal. The object has dimensions
of a = 1.55 ft , where a is the diameter of the semi-
circle,b = 3.74 ft, and c = 2.35 ft . A hole with diameter
d = 0.750 ft is centered at (1.26, 0.775).

You are a biomedical engineer working for a small orthopaedic firm that fabricates rectangular shaped fracture
fixation plates from titanium alloy (model = "Ti Fix-It") materials. A recent clinical report documents some problems with the plates
implanted into fractured limbs. Specifically, some plates have become permanently bent while patients are in rehab and doing partial
weight bearing activities.
Your boss asks you to review the technical report that was generated by the previous test engineer (whose job you now have!) and used to
verify the design. The brief report states the following... "Ti Fix-It plates were manufactured from Ti-6Al-4V (grade 5) and machined into
solid 150 mm long beams with a 4 mm thick and 15 mm wide cross section. Each Ti Fix-It plate was loaded in equilibrium in a 4-point bending
test (set-up configuration is provided in drawing below), with an applied load of 1000N. The maximum stress in this set-up was less than the
yield stress for the Ti-6Al-4V…

Task 1
You are employed as a mechanical engineer within an unnamed research center, specializing in the
development of innovative air conditioning systems. Your division is tasked with providing computer-based
modeling and design solutions using computational fluid dynamics through ANSYS software. Your primary
responsibilities involve the analysis of horizontal channel dynamics to meet specific criteria. Under the
guidance of your immediate supervisor, you have been assigned unique responsibilities within an ongoing
project. As a member of the research team, your role includes constructing an appropriate model and
executing a sequence of simulation iterations to explore and enhance channel performance. Figure 1
provides a visualization of the horizontal channel under consideration. Consider 2D, incompressible, steady
flow in a horizontal channel at a Reynolds number of 150. The schematic below illustrates the channel flow,
not drawn to scale. For simplicity, neglect gravity. The…
