Chapter 1, Problem 1RQ
Temperature is defined as
A. how hot it is.
B. the level of heat.
C. how cold it is.
D. why it is hot.
Expert Solution & Answer
To determine
The definition of temperature.
Answer to Problem 1RQ
The temperature is defined as the level of heat.The correct option is (b)
Explanation of Solution
The temperature is defined as the degree of hotness or coldness of an object. But according to the question, temperature can also be defined as the level of heat.
Consider an example of a glass filled with boil water and ice cream. Here, ice cream is colder than the glass of boiling water with respect to atmosphere. Temperature is usually measured by thermometer. Thermometers can be classified into three types on the basis of the units of the temperature. They are as follows-
- Celsius thermometer.
- Fahrenheit thermometer.
- Kelvin thermometer.
The Celsius thermometer is used to measure the temperature in degree Celsius.
The Fahrenheit thermometer is used to measure the temperature in degree Fahrenheit.
The Kelvin thermometer is used to measure the temperature in Kelvin.
Conclusion:
Hence, the correct option is (b).

1. Draw the moment (M), axial (N), and shear (S) diagrams. Please note that this is a 3D problem and you
will have moment (M) and shear (S) along two different axes. That means that you will have a total of 5
diagrams.
I tried solving this one but have no idea where I went wrong can you please help me out with this?
Question 1.
A tube rotates in the horizontal xy plane with a constant angular velocity w about the z-axis. A
particle of mass m is released from a radial distance R when the tube is in the position shown.
This problem is based on problem 3.2 in the text.

a) Draw a free body diagram of the particle if the tube is frictionless.
b) Draw a free body diagram of the particle if the coefficient of friction between the sides of the
tube and the particle is μs = flk = fl.
c) For the case where the tube is frictionless, what is the radial speed at which the particle
leaves the tube?
d) For the case where there is friction, derive a differential equation that would allow you to
solve for the radius of the particle as a function of time. I'm only looking for the differential
equation. DO NOT solve it.
e) If there is no friction, what is the angle of the tube when the particle exits?
• Hint: You may need to solve a differential equation for the last part. The "potentially…
