Question

A bolt extends through 3/4” thick plywood, a washer that is 1/8” thick, and a nut that is 3/16” thick. The bolt should be 5/8” longer than the sum of the thickness of the plywood, washer and nut. What is the minimum length of the bolt?

Answer 1

(3/4" +1/8" +3/16" +5/8") = (12 +2 +3 +10)/16" = 1 11/16"

The bolt needs to be a minimum of 1 11/16 inches in length.

Answer 2

Answer:

Minimum length of bolt $=\left (\frac{27}{16} \right )^"$

Step-by-step explanation:

The bolt should be $\frac{5}{8} "$ longer than the sum of the thickness of the plywood, washer and nut.

Thickness of the plywood = $\frac{3}{4} "$

Thickness of the washer = $\frac{1}{8} "$

Thickness of the nut = $\frac{3}{16} "$

Length of bolt = Thickness of the plywood+Thickness of the washer+Thickness of the nut$+\left (\frac{5}{8} \right )^"$

Minimum length of bolt $=\frac{3}{4}+\frac{1}{8}+\frac{3}{16}+\frac{5}{8}=\frac{12+2+3+10}{16}=\left (\frac{27}{16} \right )^"$
