Chapter 6, Problem 1RQ
Three types of nails are _______, ________, and _____.
Expert Solution & Answer
To determine
The type of nails.
Answer to Problem 1RQ
Three types of nails are Finishing nail, roofing nail and Masonry nail.
Explanation of Solution
There are three types of nails as follows:
- Finishing Nail:
These nails have small head and can be driven into the wood below its surface. The figure below illustrates a masonry nail.
- Roofing Nail:
These nails are very useful to join shingles and roofing material to the roof. Roofing nails have large head. In apartments for fastening things these nails are used. Figure below illustrates a roofing nail.
- Masonry nail:
This type of nails is used to fasten things in the masonry. They have moderate head size. Figure below Illustrates a masonry nail.
Conclusion:
Thus, three types of nails are Finishing nail, roofing nail and Masonry nail.

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…
