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

Minimum length of bolt
`=\left ((27)/(16) \right )^`

Explanation:

The bolt should be
`(5)/(8)` longer than the sum of the thickness of the plywood, washer and nut.

Thickness of the plywood =
`(3)/(4)`

Thickness of the washer =
`(1)/(8)`

Thickness of the nut =
`(3)/(16)`

Length of bolt = Thickness of the plywood+Thickness of the washer+Thickness of the nut
`+\left ((5)/(8) \right )^`

Minimum length of bolt
`=(3)/(4)+(1)/(8)+(3)/(16)+(5)/(8)=(12+2+3+10)/(16)=\left ((27)/(16) \right )^`

Answer 2

(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.
