Calculate the first moment of Area of point A relative to the neutral axis of the cross section.  A is located 30 mm from the top of the cross-section.

A beam has both bending moment and shear force acting. Which statement is true?

At the end of this exam I will hold each of my exam sheets up in front of the Honorlock camera for about 2 seconds peer sheet. Each sheet will be held flat and zoomed in enough to where details can be visible. I will also upload the sheets as one pdf file at the end of the exam – in the last exam upload question.  Note: Only the uploaded file will be graded. Holding the images up to Honorlock camera is for verification purposes only. 

At a point on the free surface of a steel automotive component [E = 29,700 ksi,ν = 0.29], a strain rosette was used to obtain normal strains of εa = 241 με, εb = –425 με, and εc = 44 με. Determine normal strain εx at the point.

At a point on the free surface of a steel automotive component [E = 28,100 ksi,ν = 0.18], a strain rosette was used to obtain normal strains of εa = 43 με, εb = –290 με, and εc = 61 με. Determine normal strain εx at the point.

At a point subjected to plane stress on the surface of a structural member, the stresses are σx = –10 ksi, σy = –5 ksi, and τxy = 6 ksi. Determine the magnitude of the absolute maximum shear stress at the point.

At a point subjected to plane stress on the surface of a compressed air cylinder, the stresses are σx = –50 MPa, σy = –80 MPa, and τxy = 60 MPa. Determine shear stress τnt at the point for a counterclockwise coordinate rotation of 11°.
