What i understand from the statement given is that the expression will be:
10m + n/4
where m = 5 and n = 16
now by putting the values of m and n in the expression,we get
10(5) + 16/4
=50 + 4
= 54
Thus, after solving the expression we get the answer 54.
It would vibrate, and at enough force it could break it loose from its supports.
