2. Introduction
This lab was about adding vectors,
balancing forces and learning how to
use the force table.
3. Objectives
To reinforce what we have learned about
adding vectors, resultants and equilibrant
forces.
To gain some experience using a simple force
board.
4. Procedure
What we did first was that we set up the force
table.
What we did next was that we set up the
table for the trial 1.
1. Since we were using metric masses, we added
200 g. to the three ends of both string 1 and 2. We
added 350 g. to string 3.
2. After this, we arranged the pulleys so that string
1 was positioned directly over the 0° mark and
string 2 is positioned over the 55° mark.
5.
6. 3. After that we moved the third pulley until the
ring in the center was exactly centered over the
peg.
4. Later, we estimated the angular position of
string 3 to the nearest tenth degree and recorded
the measurement under Direction of F 3 in Table 1.
7. Trial 2
1. We replaced the mass on string 1 with a mass of
150° but kept the pulley at 0°.
2. After that, we added 50 g. to the 200 g. mass on
string 2 and moved the pulley to 65.0° .
3. We placed string 3 approximately over the mark
of 340°.
4. Then, we moved string 3 and added additional
mass to the string as necessary until the ring was
centered over the peg.
5. Finally we recorded the magnitude of the force
for each string and the direction of the third stting
in Table 1.
9. Conclusion
As a conclusion we can tell that we were able
to see how mass can affect the magnitude
and direction of a force.
We also learned to used the force scale.
