Assuming that the material obeys Hooke's Law and that it is circular in cross section, find the specified values in the table:

Diameter / m, m,mm	Cross sectional area / m, squared,m2	Original length / m,m	Tension / N,N	Extension / m, m,mm	Stress / M, P, a,MPa	Strain	Young's modulus / G, P, a,GPa
(a)	(b)		9, point, 8,9.8		(c)	0, point, 40, percent,0.40%	130,130

Part A

Diameter

a) Diameter in m, m,mm?

b)Cross sectional area in m, squared,m2?

c) Stress in M, P, a,MPa?
