Chapter 26, Problem 1RQ
The two broad categories of display cases are _______and _______.
Expert Solution & Answer
To determine
The two broad categories of the display cases.
Answer to Problem 1RQ
The two broad categories of display cases are open and closed.
Explanation of Solution
The display case is a cabinet made up of a transparent material. It is used to display objects for viewing. It can be seen in restaurants, stores, or maybe in a house.
Display cases are also used in retail stores to preserve food and other things, which are displayed to the customers for sale. The customers can select items from the section of the store and choose any of them to purchase. Some of the display cases are open which allows the customer to reach in without opening a door. The closed display cases are more energy efficient as compared to open display cases. These display cases are available in different temperature ranges such as low, medium, and high-temperature range. An open display case maintains temperature conditions. This is because the refrigerated air is heavy and it gets settled at the bottom. This is achieved by designing and maintaining air patterns, which keep the refrigerated air from leaving the case.
Conclusion:
The two broad categories of display cases are open and closed. Both of them have their own characteristics as explained earlier.

If the coefficient of static friction between his shoes and the ground is \( \mu_s = 0.4 \) and between the crate and the ground is \( \mu_c = 0.3 \), determine if the man is able to move the crate using the rope-and-pulley system shown. **Diagram Explanation:** The diagram illustrates a scenario where a man is attempting to pull a crate using a rope-and-pulley system. The setup is as follows: - **Crate (C):** Positioned on the ground with a rope attached. - **Rope:** Connects the crate to a pulley system and extends to the man. - **Pulley on Tree:** The rope runs over a pulley mounted on a tree which redirects the rope. - **Angles:** - The rope between the crate and tree forms a \(30^\circ\) angle with the horizontal. - The rope between the tree and the man makes a \(45^\circ\) angle with the horizontal. - **Man (A):** Pulling on the rope with the intention of moving the crate.
