Free Mechanical Aptitude Tools Question and Answers

Question 1

Used to add more torque when driving screws or manually drilling holes in wood. Several bits are compatible with this tool.

Accepted Answer

Brace

Answer

A brace, often called a brace and bit, is a hand-powered tool specifically designed to provide significant torque for drilling holes and driving screws, particularly in woodworking. Its crank handle and chuck mechanism allow for greater leverage and control compared to simpler hand drills. It accommodates various bits, including auger bits and screwdriver bits, making it versatile for manual drilling and fastening tasks.

Question 2

Used to measure the amount of electrical current flow (calibrated in amperes).

Accepted Answer

Ammeter

Answer

An ammeter is an electrical instrument specifically designed to measure the flow of electric current in a circuit. It is calibrated in amperes (A), which is the standard unit for electric current. To measure current, an ammeter must be connected in series with the circuit component through which the current is to be measured.

Question 3

Used to determine a true horizontal line or accurate level of a surface.

Accepted Answer

Answer

A level, commonly known as a spirit level or bubble level, is a tool specifically designed to indicate whether a surface is perfectly horizontal (level) or vertical (plumb). It contains a liquid-filled vial with a bubble that, when centered between two marks, signifies a true horizontal or vertical alignment. This tool is essential in construction, carpentry, and many other trades for ensuring accuracy.

Question 4

Used to drive screws with a Phillips head. Compared to grip obtained with traditional slotted- or flared-tip screwdrivers, its design improves grip.

Accepted Answer

Philips Screwdriver

Answer

A Phillips screwdriver is specifically designed to fit screws with a Phillips head, which features a cross-shaped recess. This design allows for better grip and reduces the tendency for the screwdriver to cam out (slip out of the screw head) compared to traditional flat-head screwdrivers. The improved grip makes it easier to apply torque and drive screws effectively.

Question 5

Used to grasp and rotate pipes without scratching the external coating.

Accepted Answer

Strap Wrench

Answer

A strap wrench is a specialized tool designed to grip and turn round objects, such as pipes or filters, without marring their surfaces. It uses a strong, flexible strap (often made of rubber or nylon) that wraps around the object, providing a secure, non-slip grip. This prevents damage to polished finishes or delicate coatings that traditional metal wrenches might scratch or deform.
