A steel bracket is loaded as shown below by a force $P=2kN.$ The dimensions are given as $a=20mm,b=16mm,$ and $d=44mm.$

Determine the normal stress due to force $P$ at point $A.$ Express your answer in units of MPa with one decimal place of accuracy. Compressive stress should be entered as negative and tensile stress

should be positive.

${}_A=$MPa

Determine the normal stress due to force P at point B$.$ Express your answer in units of MPa with one decimal place of accuracy. Compressive stress should be entered as negative and tensile stress

should be positive.

${}_B=|,$MPa

Determine the resultant compressive force acting in the bracket at cut ABD due to the compressive normal stress. Express your answer in units of $kN$ with one decimal place of accuracy.

$R=kN$
