Two steel bars are joined using a belled fitting and a rectangular pin as shown. Knowing that $P=16kN$ and the diameter of the bars is $d=10mm,$ determine the minimum yield strength of the bars, for which a Factor of Safety of F$.$S$.=1\mathrm{.}5$ is maintained against yielding. Enter your answer below in MPa, rounded to the nearest MPa.

For your written solution to this problem, also determine the following:

The shear stress in the pin if the thickness of the pin is $t=5mm.$

The required wall thickness for the bell if the bearing stress between the pin and bell cannot exceed ${}_{b_{\text{a}\text{l}\text{l}\text{o}\text{w}}}=250$MPa.

The maximum normal stress in the bell for the wall thickness determined above. Note that the maximum normal stress in the bell will occur where the hole in the walls of the bell occurs to allow the pin to pass through.
