When using a drill, the first thing you do is
Correct Answer
A. Make sure the diameter of the hole to be drilled is within the capacity of the drill
Explanation
Before using a drill, it is important to ensure that the diameter of the hole to be drilled is within the capacity of the drill. This is necessary because drills have specific limitations in terms of the size of holes they can effectively drill. If the diameter of the hole exceeds the drill's capacity, it can lead to damage to the drill or ineffective drilling. Therefore, it is crucial to check and confirm that the drill is capable of handling the desired hole size before proceeding with the drilling process.

Which diameter (in inches) electric saw blade is the most common found in maintenance activities?
Correct Answer
B. 8
Explanation
The most common diameter of an electric saw blade found in maintenance activities is 8 inches. This size is widely used because it strikes a balance between being large enough to handle most cutting tasks efficiently, while still being manageable and easy to use. Blades that are too small may not be able to cut through thicker materials effectively, while blades that are too large can be difficult to control and may cause unnecessary strain on the saw. Therefore, an 8-inch blade is the most commonly preferred size for maintenance activities.
3.
An electric saw's blade must be operationg at what speed before it contacts the material being cut ?
Correct Answer
A. Full
Explanation
The blade of an electric saw must be operating at full speed before it contacts the material being cut. This is because a slower speed may cause the blade to get stuck or not cut through the material effectively. A moderate or accelerated speed may also lead to a loss of control over the saw, increasing the risk of accidents. Therefore, operating the saw at full speed ensures efficient cutting and minimizes the chances of any mishaps.

Hoist hooks must be replaced when they have more than
Correct Answer
C. 15 percent in excess of normal throat opening or more than 10º twist from the plane
Explanation
Hoist hooks must be replaced when they have more than 15 percent in excess of normal throat opening or more than 10º twist from the plane. This is because exceeding these limits can compromise the integrity and safety of the hook. The throat opening is the space between the hook's tip and the bottom of the throat, and exceeding 15 percent of the normal throat opening could indicate wear or damage. Similarly, a twist of more than 10º from the plane could cause the hook to be misaligned and potentially fail under load. Therefore, it is important to replace hoist hooks that exceed these limits to ensure safe lifting operations.
