SUMMARY

When a heavy object is suspended from a spring and the spring is rotated, the dynamics involve both centripetal and gravitational forces. The centripetal force, calculated as mv²/r, acts horizontally, while the vertical component of the spring force counteracts the weight of the object. To determine the resultant spring force, one must apply Hooke's Law to find the extension of the spring. This analysis combines principles of circular motion and elasticity in physics.

PREREQUISITES
  • Centripetal force calculations
  • Hooke's Law for spring mechanics
  • Basic principles of circular motion
  • Understanding of forces and motion in physics
NEXT STEPS
  • Study Hooke's Law and its applications in mechanical systems
  • Explore centripetal force and its role in circular motion
  • Investigate the effects of mass and radius on rotational dynamics
  • Learn about energy conservation in rotating systems
USEFUL FOR

Physics students, mechanical engineers, and anyone interested in the dynamics of rotating systems and spring mechanics.

hi,
what happens, when I hand on a spring a heavy object and then we'll rotate the spring? I've tried to write down some maths for it but I don't know anyway...

It's the same as rotating the object hung on a rope: if swung in a horizontal circle at constant speed, v, the centripetal force is mv^2/r, which is the horizontal component of the spring force, and the verticlal force component of the spring force is the weight of the object. Once you calculate the resultant spring force, use Hooke's law to determimne its extension.
