Solving Complex Structural Challenges - Can a 1000kg Lift Force Lift 950kg?

Click For Summary
SUMMARY

The discussion revolves around the feasibility of a 1000kg lift force being able to lift a 950kg weight using a wedge system with low friction due to lubrication. The scenario includes an additional weight of 1030kg that causes the structure to move downward, and the removal of this weight creates an upward force on the 950kg weight. The wedge is designed to provide additional lift and is anchored to a solid base, allowing movement only within the radius of the attached pole. Key considerations include the balance of forces and the impact of friction on the lifting capability.

PREREQUISITES
  • Understanding of basic physics principles, particularly forces and equilibrium.
  • Familiarity with Fred Body Diagrams for analyzing forces in a system.
  • Knowledge of mechanical advantage and how wedges function in lifting scenarios.
  • Experience with concepts of friction and its effects on movement in mechanical systems.
NEXT STEPS
  • Study the principles of static and dynamic equilibrium in mechanical systems.
  • Learn how to create and interpret Free Body Diagrams for complex structures.
  • Research the mechanics of wedges and their applications in lifting forces.
  • Explore the effects of lubrication on friction and its implications in engineering designs.
USEFUL FOR

Mechanical engineers, physics students, and anyone involved in structural analysis or lifting mechanisms will benefit from this discussion.

hi, i have this problem that i am trying to figure out, but seems i need some help..:)

ii have attached an image and an animation to clearly explain my problem.
what i am trying to understand is will the green base with its 1000kg lift force be able to lift the pole with the red dot (950kg) above the wedge,provided that that the friction of the wedge is very low due to lubrication.\
in fig.1 - an additional weight is added to make the upper part heavier (1030kg) causing the entire structure to move down.
in fig 3 - the additional weight is removed causing the disbalance in weight and pushing the red weight upward. the wedge is in place to act as extra lift ( the wedge is connected with a pole to a solid base, thus allowing the wedge to only move within the radius of the pole it is attached to.

let me know if you have questions.

How would you first approach this problem, alibaba? Have you been able to draw some Fred Body Diagrams?
