Question

( 4) Figure: ДА EBD : суу ме, а с MAY Tyy= M ( MAEC х4 м , , сүт - Маус бууі 4 ту: 10 :

From the figure, a FBD is drawn and the stresses at point A are calculated symbolically. Please explain in words how the subscripts for each stress are determined, based on the given axis orientation.

Answer 1

Oyy =) Normal stress acting in y direction in Y-plane I F = Ay =) Normal force acting along 4-direction A =) Area of crossection in the same direction. 642 ) Shear stres acting in Yedirection in 2-plane vo) Transverse shear force Q=) fingit moment of farea section above, 2) I s) Moment of inertia ba) width of the section ta) Shear stress in the specified direction Oyna Mc. Magic 8. Oyy ) Benling stress Normal stres) in y direction in Y-plane Moment about the neutral arts Mas

- C=) the perpendiculas distance from the Ontermost fiber to the neutral axis. 1) Moment of thertia, in specified direction Max 2) Moment of A about the neutral axis in x-direction [Gay = Me More 644 ) Bending stres (Normal stress) in ydirection in y-plane: MAZ = Moment of A about the neutral axis in za direction. I ) Moment of inertia in the specified direction. TGV 1 1 Opz =) Shear stress acting in 7-direction in a plane. 1) Torque acting in y-direction r Radial distance of point from neutral asis 3. =) Polar moment of inertia. May y Moment of A be about the neutral . aris in y-direction, na I a Moment of inertia in specified direction.
