A steel bracket is loaded as shown below by a force $P=4kN.$ The dimensions are given as $a=14mm,b=14mm,$ 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.
