Behaviour of Springs and Materials

If a metal wire is supported at the top then a weight attached to the bottom, it
stretches. The weight pulls down with force F, producing an equal and opposite
force at the support. Deformation only happens when a pair of opposite forces act.

Wear safety goggles, ping!
Use as long and thin a wire as possible, as it will extend more for the same force, (reduces

1. Find the smallest weight necessary to straighten the wire, (found by placing masses on a
balance and multiplying by g to find the force).

The material does not deform plastically, deforms elastically very little
When stress is applied to a brittle material any tiny cracks in the material's surface get bigger
until the material breaks, this is called brittle fracture.
