You have been asked to do some research and development work on part of a new design that uses the plate arrangement shown below.

Calculate the minimum diameter bolt in millimetres that can be used in the clevis shown. Round your final answer to the nearest whole mm$.$

The force applied to the bolt is $200$ kN and the shearing strength of the bolt is $200$ MPa.

Tip: convert millimetres to metres first.

Use the following single shear formulae:

Shear Strength $($MPa$)=$ Force $($N$)/$ Cross Sectional Area $($m$2)$

Therefore, cross sectional area $=$ Force $/$ Shear strength $=$

Area $=$

$($assume $\backslash$pi $=3\mathrm{.}142)$

Therefore, r $==$
