Problem Set $6$

$1)\backslash ($ A $5\backslash$mathrm$\{$kN$\}\backslash )$ force is applied to a solid cylinder of radius $20$ mm $.$

a$.$ Determine the normal and shearing stresses at H and K $.($Answer: See figure below$)$

b$.$ Draw the Mohr Circle and find the principal stresses and maximum shearing stress. Clearly show the orientations as well. $($Answer: Maximum shearing stress for H and K are $40\mathrm{.}6$ MPa and $13\mathrm{.}3$ MPa $,$ respectively. For principle stresses and orientations, see figure below.$)$
