Question 1

Two technicians are discussing wrenches. Technician A says that fingers should be wrapped around the handle of an open-end wrench if the wrench needs to be pushed toward an obstruction. Technician B says that an open-end wrench holds a bolt head better than a box-end wrench. Who is correct?

Accepted Answer

Technician A's advice is incorrect because when pushing a wrench towards an obstruction, it's safer to keep fingers away from the handle to avoid injury. Technician B is also incorrect because a box-end wrench typically provides a better grip on a bolt head than an open-end wrench, due to its enclosing design.

Question 2

Adjustable wrenches are as strong as standard open-end wrenches.

Accepted Answer

Adjustable wrenches are not as strong as standard open-end wrenches because they have moving parts that can wear down over time and cause the jaws to slip, whereas open-end wrenches have a solid, fixed end that provides more torque and grip on the nut or bolt.

Question 3

Rubber mallets are used for driving pilot pins.

Accepted Answer

Rubber mallets are typically used for gentle tasks that require a softer blow to avoid damaging the workpiece, not for driving pilot pins which usually require metal hammers for sufficient force.

Question 4

Wheel blocks should always be placed in front and behind a tire.

Accepted Answer

Wheel blocks are placed in front and behind a tire to prevent the vehicle from moving.

Question 5

Multimeters _____.

Accepted Answer

Multimeters for automobiles should have high impedance to prevent damage to sensors and electronic components.

Question 6

Two technicians are discussing computerized service information. Technician A says that paper manuals are much less expensive to maintain. Technician B says that most paper service manuals have been replaced by computerized data systems. Who is correct?

Accepted Answer

Technician B is correct. Most paper service manuals have been replaced by computerized data systems for several reasons, including easier updating, greater accessibility, and reduced physical storage requirements. While it is true that paper manuals may be less expensive to maintain in terms of initial cost, they can become outdated quickly, requiring constant updates and reprints, which can add up over time.

Question 7

Two technicians are discussing automotive jacks. Technician A says that floor jacks are the most common jack found in automotive shops. Technician B says that most floor jacks in shops are rated between six and eight tons. Who is correct?

Accepted Answer

Technician A is correct because floor jacks are indeed the most common type of jack found in automotive shops due to their versatility and ease of use. Technician B is incorrect because most floor jacks in shops are typically rated for much less than six to eight tons, commonly around 2 to 3 tons for passenger vehicles.

Question 8

A reamer is used when a hole must have a precision fit.

Accepted Answer

A reamer is a cutting tool used to enlarge and smooth out holes that require a high degree of precision, such as those used in machinery or engines. The reamer is designed to remove only a small amount of material at a time, ensuring that the hole will have a precise fit for a specific size of bolt or other fastener.

Question 9

Combination pliers are the least common type of pliers used.

Accepted Answer

Combination pliers are actually quite commonly used, as they can be used for a variety of tasks such as cutting, gripping, and twisting.

Question 10

Two technicians are discussing adjustable wrenches. Technician A says that the length of the wrench handle does not determine how wide the jaws open. Technician B says that adjustable wrenches are sized by the wrench handle. Who is correct?

Accepted Answer

The answer of Two technicians are discussing adjustable wrenches. Technician...

Question 11

The size of a wrench is determined by the nut or bolt head it fits on.

Accepted Answer

The size of a wrench is determined by the nut or bolt head it fits on. Different sized nuts and bolts will require different sized wrenches.

Question 12

Box-end wrenches have less chance of slipping off than an open-end wrench.

Accepted Answer

Box-end wrenches have a closed shape that grips the entire circumference of a bolt or nut, making them less likely to slip off compared to open-end wrenches that only grip two flat sides.

Question 13

Two technicians are discussing vacuum testers. Technician A says that vacuum testers are not designed to diagnose engines. Technician B says that vacuum testers will not work on a computer controlled vehicle. Who is correct?

Accepted Answer

Vacuum testers are indeed designed to diagnose engine problems by measuring the vacuum pressure in the intake manifold, which can help identify issues such as leaks or performance problems. They can also be used on computer-controlled vehicles, as these vehicles still rely on vacuum for various systems and the diagnostic principles remain the same.

Question 14

What statement is true concerning lifts?

Accepted Answer

Automotive lifts are designed to make work easier by allowing mechanics to access the underside of vehicles without having to crawl underneath them.

Question 15

Vise grip pliers are compound-lever pliers that can be locked to the part.

Accepted Answer

Vise grip pliers have a mechanism that allows them to be locked onto the part being gripped, making them very useful in situations where a secure hold is required. The compound-lever design of these pliers allows for greater leverage, making them easier to use and more effective than traditional pliers.

Question 16

Offset screwdrivers are designed to work in tight spaces.

Accepted Answer

Offset screwdrivers have a bent shaft that allows them to reach screws in tight spaces where a straight screwdriver cannot.

Question 17

Which type of wrench goes entirely around a nut or bold head?

Accepted Answer

A box-end wrench has a closed loop design that goes entirely around the nut or bolt head. This provides a more secure grip and reduces the likelihood of slipping or rounding off the corners of the fastener.

Question 18

What statement is true concerning service information?

Accepted Answer

Some service information, such as technical service bulletins, may be specific to a certain vehicle identification number (VIN) or range of VINs.

Question 19

Two technicians are discussing multimeters. Technician A says that multimeters can test almost any circuit on a car. Technician B says that multimeters should be high-impedance. Who is correct?

Accepted Answer

Technician A is correct in stating that multimeters can be used to test almost any circuit on a car. Technician B is also correct in stating that multimeters should be high-impedance. High-impedance multimeters are less likely to interfere with the circuit being tested and can provide more accurate readings. Therefore, both technicians are correct.

Question 20

Sliding T-handles can be used to drive a socket.

Accepted Answer

Sliding T-handles are designed to be used with sockets to apply torque to bolts and screws. The sliding mechanism allows for easy switching between tightening and loosening operations, making them a versatile and essential tool in many industries.
