Maximum principal stress theory is applicable to

• Composite materials

• Ductile materials     

• Brittle materials

Under maximum principal stress theory, maximum principal stress is equal to

• Allowable stress in tension

• Allowable stress in compression

• Allowable stress in shear

Maximum principal strain theory is also called as

• St Venit's theory

• Haigh theory

• St.Venant’s theory

A ductile material may not meet a failure if it has been tested for the theories of failure

• Firstly Maximum Principal Theory

• Secondly Maximum Principal Strain Theory

• Thirdly Maximum principal strain energy theory

• None

Finding allowable stress after the application of theories of failure ensures

• Lapses in design

• Soundness of design

• breakage of material

• both soundness and lapses in design

Under complex or simple loading, strain energy is

• External work done

• Internal work done

• either internal or external

• neither internal or external

Under complex loading, theories of elastic failures ensure

• stability

• instability

• both stability and instability

• fracture

Under complex loading, theories of elastic failure establishes the

(a)

(b)

(c)  Both (a) & (b)

• Margin of failure

• Margin of safety

• both margins of failure and safety

Theories of elastic failure help to recognize

• weakness of materials

• strength of materials

• properties of materials

• both strength and weakness of materials

How power transmission associated to angular velocity

• angular velocity increases directly to power transmission

• power transmission independent on velocity

• power transmission is inversely related to velocity

• these two variables has no relation
