Case 1 traffic light:Weight of hanging object: 370gAngle 1: 130 degrees Angle 2: 100 degrees Measured tension 1: 3.0 NMeasured tension 2: 4.2 N Please answer with equations and calculations. Case 1: Traffic LightA traffic light is hanging from two wires set at known angles. What is the magnitude of the tension in each wire?Set up this system based on the figure. Hang an object of known mass from the center of a meter-long string with loops on both endsfor attaching the spring scale. It may be easier to tie a second shorter string to the center of the first string and tie the object to theshort string. Hold the long string in such a way that two different angles, 8₁ and 92, are formed. It may be helpful to have an assistant,or tie one end of the string to a fixed object.Case 1 Example 1An experimental example of the Traffic Light word problem.Record the mass or weight of the object and the two angles on the Report Sheet and solve for the two tensions. You can set the systemdown while you are doing this, or you can immediately measure the two tensions before doing the calculation. If you measure thetensions last, be sure to re-create the system with the exact same angles.Show AllCarefully attach the spring scale to one end of the string by holding the loop with the hook, making sure that the two angles of thestring have not changed. Record the tension, T₁, on the Report Sheet. Repeat this procedure for the other end of the string, recordingthe second tension, T₂, on the Report Sheet.Case 1 Example 2An experimental example of the Traffic Light word problem with the spring scale attached.Compare the calculated tensions with the experimental values measured by the spring scale.Note: This system is only vector addition and does not require the calculation of torques.Show All The three conditions of static equilibrium are:Lesson 12 Lab: Static Equilibrium●●Introduction●MaterialsIn words, the sum of all the forces acting in the x-direction is zero; the sum of all the forces acting in the y-direction is zero;and the sum of all the torques is zero.IntroductionIn this experiment, we will verify the static equilibrium conditions by re-creating three static equilibrium word problems. Thechoice of force magnitudes, points of application and angles will be a matter of personal choice. The goal is to calculate allforces for each system and compare the results to measured values.Data Collection...Statics Report Sheet (Download and print)A meter stick or yardstickA 5.0 N spring scaleCase 1 Example 1ΣF = 0ΣF, = 0ΣΤ = 0● StringThree objects with masses between 100-500 gramsA ruler and protractorConclusionsMaterialsData Collection and AnalysisCase 1: Traffic LightA traffic light is hanging from two wires set at known angles.
