Cantilever Deflection

Preliminary Work

                                     

The more weight there is on the ruler,

The more deflection there is.

Prediction

I predict, that as the mass increases, the deflection of the ruler will increase. I think this because, the more mass on the ruler, will result to more weight, therefore there would be a larger force acting down on the ruler, causing an unbalanced moment, which will cause the ruler to deflect.

Due to my preliminary results, I have realised t hat, if I double the mass on the ruler, the ruler will almost double in deflection. Therefore, if I were to plot a graph from my results, I would find that I would get a straight-line graph going through the origin, as the ruler deflects in proportion.

Variables/Factors

  • The mass on the ruler – I am going to increase this, starting from 0.1kg, increasing it in steps of 0.1kg, up to 1.0kg.
  • The deflection of the ruler – I am going to place certain amounts of masses on the ruler, and then I am going to measure the deflection of the ruler.
  • The heaviest mass that I am going to place on the ruler – The heaviest mass that I am going to place on the ruler is 1.0kg, this is because if I place a heavier weight on to the ruler, it is ...
