Homework Statement
Finding the mass of the meterstick!
Distance was found through experimentation
I am given a mass hanger of 50g to place on a 100cm ruler held up on its center of mass at 49.8cm
I displace the clip holding the ruler by 15cm to the left. (assuming the ruler counts up from left to right) The experimental value in practice was 13.1cm for a balanced ruler. (How am I to calculate the assumed value?) With this information how am I to calculate the mass of the meterstick?
If not sufficient information is given or hard to imagine I could draw a picture and upload it.
Homework Equations
Mass of ruler: 95.1 g
τ = rfsinθ
Ʃ F = 0
Ʃ τ= 0
The Attempt at a Solution
I don't know what to plug in, I also think I am missing an equation. Trying to visualize the problem, I see how moving the clip to the left that I am increasing the torque in the problem, and to balance the meterstick, I must place the 50g mass at a certain distance to achieve equal amount of torque on both sides of the meterstick thus achieving equilibrium and a balanced meterstick. Am I missing something for finding the mass?
