Question 1

What does the hardness rating on a grinding wheel (such as 'A' for soft to 'Z' for hard) indicate?

Accepted Answer

How firmly the abrasive grains are bonded

Answer

The hardness grade on a grinding wheel reflects the bond strength holding the abrasive grains — harder grades retain grains longer.

Question 2

When cutting with a hacksaw, the blade teeth should face:

Accepted Answer

Away from the handle (forward)

Answer

Hacksaw blades are installed with teeth pointing forward (away from the handle) so they cut on the push stroke.

Question 3

Which fastener type allows a joint to be disassembled and reassembled many times without losing holding strength?

Accepted Answer

Wood screw

Answer

Wood screws can be driven in and removed repeatedly while maintaining their grip, making them ideal for assemblies that need disassembly.

Question 4

What is the purpose of a pilot hole when driving screws into hardwood?

Accepted Answer

To prevent the wood from splitting and ease screw insertion

Answer

A pilot hole slightly smaller than the screw shank relieves stress in the wood fibers, preventing splitting and reducing the torque needed.

Question 5

What is 'runout' in a drill press or lathe?

Accepted Answer

The wobble or eccentricity of a rotating spindle or chuck

Answer

Runout is the deviation of a rotating tool or chuck from true center rotation, causing vibration and inaccurate holes or cuts.
