Discussion Overview

The discussion revolves around calculating the force required to lift a weight using a frame design involving rods at various angles. Participants explore the implications of the angle of force application and its effect on the lifting mechanism, focusing on theoretical and practical aspects of force vectors and angles in a mechanical context.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant seeks help with calculating the force needed to lift a 1 Kg weight using a rod system at a fixed 45-degree angle.
  • Another participant questions where the force will be applied and the direction of that force.
  • A clarification is provided that the force will be applied at point G of rod GF, with the direction influenced by the use of a string.
  • Concerns are raised about the effectiveness of the force application, particularly whether the force vector as shown would actually lift the weight.
  • Further inquiry is made regarding how changing the angle from 45 degrees to 90 degrees or 20 degrees would affect the ease of lifting the weight, along with requests for vector illustrations and calculations.

Areas of Agreement / Disagreement

Participants express uncertainty about the effectiveness of the force application and the implications of different angles on lifting the weight. No consensus is reached regarding the calculations or the best approach to the problem.

Contextual Notes

The discussion lacks specific calculations and detailed assumptions about the mechanical setup, such as friction or the exact nature of the force application. The dependence on the angle and direction of the force remains unresolved.

Who May Find This Useful

This discussion may be of interest to individuals involved in mechanical design, physics students exploring force vectors, or those working on projects requiring an understanding of force application in angled systems.

can you please help me with this as i am confused? I am designing a frame for my project.

I have a rod GF connected to rod AB at point F at 45 Degrees. The dimensions are mentioned in the attached word file. There is a weight of 1 Kg at side resting on rod AB nead end - A.

what is the force required to lift this weight? please show the calculations.



thanks

Where will the force be applied ?
 
the force is applied at point G, of the rod GF.
 
In what direction? Is the arrow to the right supposed to be the force vector?
In that case I don't see why that force would lift the weight at all?

Also, is the 45deg angle fixed?
 
actually i am going to connect a string at point G. So the direction of force will be pretty much the direciton of arrow shown, however it can vary slightly as its a string which will be applying the force and not a solid rod.

The angle of 45 deg is fixed. will it be easy to lift the weight if the angle was 90 deg? or more difficult if the angle was only 20 deg? how would the angle and direction of force affect the lifting of weight? can you please show the vectors and calculations?
