The stress at which a material begins to deform plastically is known as

85) Which of the following is the name given to the axis of the cross-section a beam at which the bending stress is zero ?

Answer is:

Neutral axis

Explanation:

86) What is the amount of stress induced in a 5 mm steel bar of length 2 m when heated from 20 Degree C to 140 Degre C while it is free to expand ?

Answer is:

40 Pa

Explanation:

87) The maximum energy that can be absorbed per unit volume without creating a permanent distortion is called

Answer is:

Modulus of resilience

Explanation:

The strain energy stored in a body due to external loading within the elastic limit is known as resilience.

1. The maximum strain energy which can be stored in a body upto the elastic limit is called proof resilience.
2. The proof resilience per unit volume of a material is known as modulus of resilience.

88) Which of the following describes a single load or force that has a small contact area as to be negligible compared with the entire surface area of the supporting member?

Answer is:

concentrated load
