Question

The Stress vs Strain graphs for wires of two
materials A & B as
shown in the fig. If YA l YB
the Young's modules of material ,
then​

Answer 1

Answer:

figure is not shown hower the answer depends on the graph

Answer 2

we know that stress /strain = Y = slope of graph

so Ya/Yb = tan 60⁰/tan 30⁰

so tan 60⁰ / tan 30⁰ = 3

so from above Ya = 3 Yb
