Question
Where did-53.13 and -26.6 and 63.4 come from please show the work
4:10
Expianation
Given information:
The stress component along x direction as
150 MPа.
The stress component along y direction as
Oy = 30 MPa
The shear stress component as 'æy
= -80 MPa
Calculation:
Calculate the principal plane
(0,)
as shown below.
2Tzy
tan (20,)
Substitute 150 MPa for Jx, 30 MPa for Cy, and
-80 MPa for Txy.
2x(-80)
tan (20,)
150-30
tan (20,) = –1.333
20,
= -26.6° and 63.4°
= -53.13°
Op
Hence, the principal planes of the state of stress is
-26.6° and 63.4°
To determine
The principal stresses of the state of stress.
