Can anyone link me to a definition of a "firm whack"?

[newbury]

As in "When my Ford F350 starter wouldn't work the tow truck guy told me to just give it a firm whack"
And how hard is a "light tap"?

First off, how big a guy are ya? And what are you gonna whack it with?

That doesn't matter to the object getting whacked.

Right between a "hard whack" and a "light whack."

Totally false. Ever been whacked by a big guy? Much less preferable to being whacked by a small guy.

Yea sure, a firm wack will leave a clear indentation in soft wood (pine) but not 1/8 inch plate.

A lite tap will break non tempered glass, but won't chip car paint.

It all depends on how much of a mark it leaves...!

So will a firm whack bounce off oak? That's about twice the Janka rating.
And is a rap between a tap and a whack?
Where is an online source further defining this use of force on material?

/edit -
Years ago I wrote the F350 story and people got incensed about my terminology.

Yes assuming 4X4 or greater.
Now you are just picking the fly specs out of the horse poop
What is "online"?

Use your judgment since you don’t want to damage the starter. My best guess would be like driving a 12 penny nail with 16 oz hammer.
