Trial$1$: DO NOT START UNTILL YOUR PREDICTED VALUES ARE CHECKED BY YOUR

INSTRUCTOR

Place a pulley at $0$ degrees, note the pulley has a center line etched to set at the precise angle.

Attach a total load of $200$ gms $.$ including the hanger, This is F$1.$ MAKE SURE YOU INCLUDE THE

mass of HANGER

Place a second pulley at $90$ degrees and load with a total of $150$ grams, Including the hanger. This

is F$2.$

Attach a $3^("$rd $")$ pulley and load it up with mass until you get F$1,$ F$2$ and F$3$ are in equilibrium and the ring

is centered around the post. Record the experimental value and the angular positions of F$3$ on the table

below. Compare to the predicted values and find the $\%$ error. Check equilibrium by finding the X and Y

components of all vectors. What is the relationship between F$3$ and the resultant of F$1$ and F$2$ R

above?

Repeat steps $3$ and $4$ above with two other F$1$ and F$2$ as indicated in the table trial $2$ below.

TRIAL $2$:

Predicted equilibrant Force F$3$ accepted Magnitude $284\mathrm{.}5$ Direction

Experimental Equilibrant Force F$3$

$(284\mathrm{.}5)/(310)$ Direction Direction $(270^($@$))/(37^($@$))$

Please check if these answers I have are correct.
