You will also need masses, mass hangers, and a balance..
Super Pulley Force Table • • Assemble the Force Table Line up the leg screw with a threaded hole in the underside of the Force Table. • Rotate the leg clockwise (left-to-right) until it is firmly attached to the table. 2. Line up the leg screw with a threaded hole. 3. Rotate the leg into the threaded hole. Storage Leg holder clip 1. Repeat for the other legs. NOTE: Do not tighten the legs more than “finger tight”. They will be removed later for storage. • 1.
ME-9447B 012-13471A Introduction String Tie fit into the rectangular holes in the recess. Align the short “legs” with the shallow notches. Insert one “leg” into one of the rectangular holes and then press down firmly on the other side of the String Tie until the other “leg” snaps into the other rectangular hole. NOTE: Press firmly. When the String Tie is correctly inserted, the top surface of the clear plastic disk will be flush with the surface of the Force Table. 1.
Super Pulley Force Table Introduction Storage The Force Table may be stored with or without the ME-9448B Super Pulley with Clamp attached. To minimize the storage space needed for the Force Table, remove the legs by unscrewing them from the table. Store the legs in the leg holders and storage clips that are on the underside of the force table. The disassembled force tables can be stacked on top of each other.
Vector Addition Vector Addition Equipment Needed Equipment Needed Super Pulley Force Table (ME-9447B) String (spool of thread) Super Pulley Table Clamp (ME-9448B) Protractor Mass and Hanger Set (ME-8979) Metric Ruler Mass Balance (SE-8723) Sheet of paper (2) Purpose The purpose of this experiment is to use the force table to experimentally determine the force that balances two other forces.
3. Hang the following masses over two of the super pulleys and clamp the pulleys at the given angles. Table 1.1: Force Mass Angle FA 50 g (0.050 kg) 0° FB 100 g (0.100 kg) 120° FE Procedure (Experimental Method) By trial and error, find the angle for the third super pulley clamp and the mass that must be suspended over the pulley so that its weight will balance the forces exerted on the strings by the other two masses.
Question How do the theoretical values for the magnitude and direction of the equilibriant compare to the actual magnitude and direction? ® 9

Appendix The protractor on this page is a version of the degree scale on the top surface of the Force Table. It can be duplicated, trimmed, and used as an overlay on the Force Table for drawing and tracing the string positions.
