Hi, i am given a question that states;
A spring is 20cm long when a load of 10N is hanging from it, and 30cm long when a load of 20N is hanging from it.
Draw diagrams and work out the length of the spring when;
a) there is no load on it
b)there is a load of 5 N on it.
can someone explain to me how to arrive at the answer??
any assistance would be greatly appreciated!
thank you!
