Question

a body of mass 10 kg suspended from a wire of length 4 m and radius 1 by under root 5 mm calculate the stress.​

Answer 1

Of the mass is moved to one side and released from the ... of wire then find the maximum extension in the length of the ... given Ysteel=2 x 10^11 N/m^2 area of cross.

Answer 2

Answer:

Force on the wire =mg=100N

Ans a -

Stress (σ)= F/A = 100/4×10^-6

= > 25×10^6 pa

Ans b-

Strain (ϵ)= σ/y = 25×10^6 / 2 × 10^11

=> 12.5 × 10-5

Ans c-

Elongation (Δl)=strain×length=37.5×10 ^−5 m
