Name _________________________Period ____________Group Name____________________Physics LabForce Table43916605842000Purpose:The purpose of this lab is to allow students to test mathematical calculations for the equilibrium of forces using weights attached to strings on a pulley system. Rules: Do not have to attach the pulleys extremely tight, only tight enough to keep them from falling off. If they are too tight, they can damage the force table.Do not pull the needle in the middle. Do not put anything on the table.1 cm = 1 washerProcedure: Part 1:Carefully attach the three pulleys to the disk; one at 0 degrees, one at 120 degrees, and one at 240 degrees.What do you think would happen if six washers were placed on each hanger (full sentence)? 462597514414500Place six washers on the hangers and carefully place the ring over the center post. Place the thread over the pulleys and observe. Where is the center post in relation to the ring surrounding it? Was your prediction correct? Explain. Using the head-to-tail method, prove the forces are at equilibrium. Show it on graph paper:Part 2: The initial set up is shown in the chart below.

Call Mr. Hafner over and see if your equilibrant is correct. Was your prediction correct? ExplainPost Assessment Questions:A student has a force table set up with one pulley at 0° with 10 washers, one pulley at 135° with 8 washers, and has calculated that the last pulley must be put at 210°, and have 14 washers on the hanger. Is the student correct? If so, prove it using a scaled diagram. If not, determine where the pulley should be and how many washers are needed. 45148501333500Below is a diagram of vectors. Vx = 30 m/s and Vy = 200 m/s. Find the resultant vectors value (v). Solve for the initial speed in the x and y directions. 42792651143000(Hint: use SOH CAH TOA)359600515062200035960055994400050990514020800050863548514000Draw and Label the resultant and equilibrants of the following vectors. ................
