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

Sant'Agata Bolognese is a small comune in the Metropolitan City of Bologna, Emilia-Romagna, in the north of Italy. It is notable for being the headquarters of the luxury automobile manufacturer Automobili Lamborghini. It is named after Saint Agatha of Sicily.
Answer:
-Differential equation: d²T/dx² = 0
-The boundary conditions are;
1) Heat flux at bottom;
-KAdT(0)/dx = ηq_e
2) Heat flux at top surface;
-KdT(L)/dx = h(T(L) - T(water))
Explanation:
To solve this question, let's work with the following assumptions that we are given;
- Heat transfer is steady and one dimensional
- Thermal conductivity is constant.
- No heat generation exists in the medium
- The top surface which is at x = L will be subjected to convection while the bottom surface which is at x = 0 will be subjected to uniform heat flux.
Will all those assumptions given, the differential equation can be expressed as; d²T/dx² = 0
Now the boundary conditions are;
1) Heat flux at bottom;
q(at x = 0) is;
-KAdT(0)/dx = ηq_e
2) Heat flux at top surface;
q(at x = L):
-KdT(L)/dx = h(T(L) - T(water))
Technician B only is right, who says that to avoid warping the cylinder head, the engine must be cold before removing it.
<h3>What is the cylinder head doing in my car?</h3>
The main task of the cylinder head is to close the discharge chamber of the engine from the top. The upper part of the engine is reached the cylinder head, while the lower part is the engine partnership.
The cylinder head sits on the engine and shuts off the combustion chamber. The gap that remains between the cylinder head and the engine is achieved by the head gasket.
<h3>How to recognize signs of possible defects</h3>
If you notice abnormalities in the functioning of your engine, it is advisable to contact a garage as soon as feasible to prevent further injury.
- The signs of cylinder head flaws include:
- You notice a power loss of the machine
- The cooling water temperature is in the red area
- You see oil in the cooling water
- You must supply water and oil after just a short time
- You notice a bad cold start behavior
