Test: Principal Stress & Strain - 2 - Question 3

### On the element shown below in the figure, the stress in MPa are The radius of Mohr’s circle V and principal stresses σ1, and σ2 are in (MPa) respectively

Detailed Solution for Test: Principal Stress & Strain - 2 - Question 3

⇒ σ1,2 = 70 ± 50
∴ σ1 = 120 MPa
and σ2 = 20 MPa
and, radius of Mohr's circle

Test: Principal Stress & Strain - 2 - Question 4

The radius of Mohr’s circle gives the value of

Test: Principal Stress & Strain - 2 - Question 5

A body is subjected to two normal strains of magnitude ∈x = 0.003 and ∈y = 0.002. The shearing strain on a plane inclined at 30° with ∈x is

Detailed Solution for Test: Principal Stress & Strain - 2 - Question 5

Shearing strain
= (∈x - ∈y) sin2θ
= (0.003 - 0.002)sin60°
= √3/2 x 10-3

Test: Principal Stress & Strain - 2 - Question 6

Which one of the following Mohr’s circles represents the state of pure shear?

Test: Principal Stress & Strain - 2 - Question 7

A bar is subjected to a uniaxial tensile stress ‘σ’. The tangential stress on a plane inclined at θ to the bar would be

Detailed Solution for Test: Principal Stress & Strain - 2 - Question 7

Normal sress = σ cos2 θ
Tangential Stress = σ sin θ cos θ

= σ sin 2θ/2

Test: Principal Stress & Strain - 2 - Question 8

Which of the following formulae is used to calculate tangential stress, when a member is subjected to stress in mutually perpendicular axis and accompanied by shear stress?

Test: Principal Stress & Strain - 2 - Question 9

Normal stresses of equal magnitude a, but of opposite signs, act at a point of a strained material in perpendicular direction. What is the magnitude of the stress on a plane inclined at 45° to the applied stresses?

Detailed Solution for Test: Principal Stress & Strain - 2 - Question 9

Here, σx = σy = -σ and θ = 45°
∴ σθ = 0

Test: Principal Stress & Strain - 2 - Question 10

Two planes xyand yz are passing through a point in a strained material. The normal and shear stresses on xy plane are +80 MPa, -30 MPa respectively and normal and shear stresses on plane yz are +30 MPa and +30 MPa respectively. What is the angle between the planes?
