MCQs on Elasticity

1.

Tensile strain is equal to

Force per unit area
Force per unit volume
Extension per unit length
Force per unit length

2.

Hooke's law states that

the extension is proportional to the load when the elastic limit is not exceeded
the extension is inversely proportional to the load when the elastic limit is not exceeded
the extension is independent of the load when the elastic limit is not exceeded
load is dependent on extension

3.

Dimensions of strain are

[L]
[M] [L]-1 [T]-2
[L]-1
It's a dimensionless quantity

4.

At ‘yield point’ of a copper wire

the load hasn't exceeded the elastic limit yet; so, Hooke's law applies
the load has already exceeded the elastic limit and the material has become plastic
even the plastic stage has passed and the wire has snapped already
Like Brass and Bronze, Copper has no yield point

5.

Substances that elongate considerably and undergo plastic deformation before they break are known as

brittle substances
breakable substances
ductile substances
elastic substances
