Question 181General Subjects - QMED
70% to passA hacksaw blade will start a cut more easily if you _______________.
Afile a nick where the cut is to be started
Bturn the saw blade at right angles to the saw frame
Ccoat the saw blade with soap before starting the cut
Dapply maximum pressure at the start of the cut
AI Explanation
The correct answer is A) file a nick where the cut is to be started. Filing a small nick or groove where the cut is to be made helps the hacksaw blade start the cut more easily. This creates a stress concentration point to initiate the cut, rather than the blade having to slowly break through the material. The other options are incorrect - B) turning the blade at right angles may help with certain cuts, but doesn't specifically aid in starting the cut. C) coating with soap can reduce friction but doesn't help start the cut. D) applying maximum pressure can damage the blade and material, rather than starting the cut smoothly.
