The property of a material which opposes the change in shape,volume,or length is called

What is the shape of the graph of stress $\to$ strain up to the elastic limit?

Check if the following statements are True or False:
$(a)$ The magnitude of Young's modulus is proportional to the increase in length.
$(b)$ Breaking stress is known as elasticity.
$(c)$ Quartz is an almost perfectly elastic body.

Is stress a vector,scalar,or tensor?

$A$ wire can sustain a weight of $15 \, kg$. If it is cut into four equal parts,then each part can sustain a weight of ........ $kg$.

The ratio of radii of two wires of same material is $2: 1$. If these wires are stretched by equal force,the ratio of stresses produced in them is .............
