A spring of stiffness 2000 N/m is stretched initially by 10 cm from the un-deformed position. The work required to stretch by another 10 cm is
Two closed coil springs are made from the same small diameter wire, one wound on 10 cm diameter core and the other on 5 cm diameter core. If each spring had N coils, then the ratio of their spring constants should be
A spring with 25 active coils cannot be accomodated within a given space. Hence, 10 coils of the spring are cut. What is the stiffness of the new spring in relation to original spring?
