10–25. The 45° strain rosette is mounted on the surface of a shell. The following readings are obtained for each gage: ε a = −20
0(10−6), ε b = 300(10−6), and ε c = 250(10−6). Determine the in-plane principal strains.

Answer:
kindly check the drawing of the FBD of the beam with reactions at A & B. A is a pin, B is a roller in the attached picture.
Explanation:
Without further ado, let's dive straight into the solution to the question above. From the diagram of the FBD of the beam with reactions at A & B it can be shown that the reaction moment is anticlockwise while the moment is clockwise.
The system is at equilibrium and the it does not matter where you place the couple (pure) moment.
The distance from A to C can either be equal or not. If AY = 2.15 kN and M = 25.8. Then, the distance between A and B = 25.8/2.15 = 12m.
Answer:
No
Explanation:
Carnot heat engine:
Carnot heat engine is an ideal heat engine for all working heat engine.It have all processes are reversible and have four processes in which twom are constant temperature process and other two constant entropy processes.
As we know that efficiency of Carnot cycle given as follows
Where
So from above expression we can say that efficiency of heat engine does not depends on the working fluids.
