1.	Q-20 State Hooke's law. Deduce expression for young's models of a wire of length l radius cross-section loaded with a body of mass producing an exposure
Answer» Answer: Hookes law: WITHIN the elastic limit, the stress APPLIED is directly proportional to strain produced. Explanation: stress=thrust/area=F/πr^2 strain=change in length/original length=∆l/l Young's MODULUS (Y)=stress/strain =Fl/πr^2∆l

Q-20 State Hooke's law. Deduce expression for young's models of a wire of length l radius cross-section loaded with a body of mass producing an exposure

Answer»

Answer:

Hookes law:

WITHIN the elastic limit, the stress APPLIED is directly proportional to strain produced.

Explanation:

stress=thrust/area=F/πr^2

strain=change in length/original length=∆l/l

Young's MODULUS (Y)=stress/strain

=F*l/πr^2*∆l
