Question: A cylindrical rock sample with a diameter of 54 mm in the uniaxial compressive strength test

It was broken by applying a force of 160.2 kN. Since the angle between the applied load direction and the breaking surface is 30 °, the stresses acting on the breaking surface;

(a) Solve using the Mohr diagram (graphic method).

(b) Solve by analytical method.

Expert Solution

I have derived formulae for calculating the stresses on an inclined plane as shown below,

A)

Apply these formulae and calculate the stresses

b)

Plot the mohr's circle for given loading system and find the stress at inclined to 60 degrees from the x-axis

Hope this helps,

Please feel free to comment for further any queries,

all the best :)

A civil engineer is analyzing the compressive strength of concrete. Compressive strength is approximately Normally distributed with variance ? 2 = 1000 psi2 . A random sample of ? = 12 specimens has a mean compressive strength of ?̅= 3179.5 psi. Let ? be the true mean compressive strength of all specimens from this type of concrete. (a) Test ?0: ? = 3200 against ??: ? < 3200 at ? = 0.05. Give the rejection region. (b) If the true...
