QUESTION: 1

### The curve obtained by plotting the normal and shear stress is called as___________

Solution:

If the normal and shear stress corresponding to failure are plotted, then a curve is obtained .The plot or the curve is called the strength envelope.

QUESTION: 2

### Which of the following is coulomb’s strength equation?

Solution:

Coulomb defined the function F (σ) as a linear function of σ and gave the following strength equation:
S = c + σ tan φ.

QUESTION: 3

### The critical shear stress causing failure of material depends upon____________

Solution:

According to Mohr’s strength theory, the critical shear stress causing failure depends upon the properties of the materials as well as on normal stress on the failure plane.

QUESTION: 4

Theory of failure, was first proposed by____________

Solution:

The theory of failures was first expressed by coulomb in 1776 and later generalized by Mohr.

QUESTION: 5

The Mohr-Coulomb theory can be expressed algebraically by, which of the following equation.

Solution:

The Mohr-Coulomb failure theory can be expressed algebraically by the equation:τf = s = F (σ)
Where, τf = s=shear stress on failure plane, at failure=shear resistance of material
F (σ) = function of normal stress. Use Code STAYHOME200 and get INR 200 additional OFF Use Coupon Code
