Homework Statement
When a mass "m" is hung from the centre of a horizontal wire, length "L". How far will the centre of the wire stretch downwards, in terms of m, L, E (youngs modulus) and A (cross sectional area of wire)
Homework Equations
mg = Tcosθ
When m is the mass hung from the wire
And T is tension in the wire
F=EAΔL/Lo
Where E is youngs modulus
F will be the tension in the wire?
ΔL is the amount the wire stretches
Lo is the original length of wire
The Attempt at a Solution
mg = Tcosθ
T=mg/cosθ
mg/cosθ=EAΔL/Lo
but is it posible to change this equation so it is only in terms M,Lo,E,A
Or find the effective spring constant of the wire
