the question is :
a steel wire of diameter 1mm is fastened horizontally to 2 rigid supports separated by 2m. the initial tension is negligible as is the sag in the wire.
A load mass 0.10kg is suspended from the midpoint of the wire, which caused the wire to deflect downwards by 2.0 cm at that point.
calculate
a) the tension in the wire
b) the young's modulus of the material of the wire
i've drawn and attached the diagram.
thanks for all the help!
