Answer:
Hello your question is incomplete here is the complete question and the attached is the required diagram and solution
Determine the equivalent state of stress on an element at the point which represents the principal stresses and the maximum in-plane shear stress and the associated average normal stress. Also, for each case, determine the corresponding orientation of the element with respect to the element shown in the figure below. Suppose that ?x = 70 MPa . (Figure 1)
. a) Determine the orientation of principal planes of stress.
Answer : The orientation of principal planes of stress are : -11.6⁰ and 78.4⁰
Explanation:
Given data from the diagram
= - 15 MPA
α = 70 MPA
The Calculation of the principal stresses and the maximum in-plane shear stress are attached below

Explanation:
Creep is known as the time dependent deformation of structure due to constant load acting on the body.
Creep is generally seen at high temperature.
Due to creep the length of the structure increases which is not fit for serviceability purpose.
When time passes structure gain strength as the structure strength increases with time so creep tends to decrease.
When we talk about Creep rate for new structure the creep will be more than the old structure i.e. the creep rate decreases with time.
