Several forces are applied to the pipe assembly shown. Knowing that $\backslash ($ Q$=260\backslash$mathrm$\{$lb$\}\backslash )$ and that the pipe has inner and outer diameters equal to $1\mathrm{.}61$ in $.$ and $1\mathrm{.}90$ in$.,$ respectively, determine the normal and shearing stresses at point $\backslash ($ H $\backslash )$ and point $\backslash ($ K $\backslash ).$

$($Enter the magnitude of each stress value below. Do not include any minus signs. Round your answers to two decimal places$).$
