Part IT (20 points) Group Score: Using the same forces from Part I, calculate the Resultant Force utilizing trigonometry/geometry. T'h.e calculations should be performed on the back of the drawing, and all work must be shown in the student’s own hand writing. Part I1I (25 points) Group Score: Before beginning Part II1, all members of the group must have completed Parts I and II and the TA has to issue the group scores. Measuring counterclockwise from 0°, position pulleys on the force table at and 120°. Using the provided string set, hang a 300g mass from the pulley at and a 200g mass from the pulley at 120°. Hang an appropriate mass on a third pulley that is strategically positioned on the force table such that the system will be in equilibrium with the knot centered on the force table. Use g=10.0 m/s>\ Also remember that F = m*a. What is the relationship between the magnitude of the Equilibrium Force and the Resultant Force you found in Parts I and I? What is the relationship between the angle of the Equilibrium Force and the angle of the Resultant Eoree voufoundin Parts I and 11? Part IV (25 points) Group Score: Your TA will remove your string set from your station, and provide you with information you will USeHONICICrine T new Equilibrium Force.
