6 USD The task.Before starting systematic measurements it is useful to do several experiments with different h and m to make sure the installation works properly.1 .Determine the acceleration of the system of connected trucks with cargo (image 1).Find the Cronstein 3.For the chosen h1 and h2 perform a series of 10 measurements of the time of the t movement of the trail system between 3 and 4 crowns.Is this data sufficient to identify a?The 2ndRepeat the experiment for all available cargoes and their different combinations.3 .Change the position of Cronstein 3 and repeat the test p.2 and p.3 for new values h1 and h2.Do the same for the third pair H1 and H2.and 4.Consider the wheels m and M. Assess the value of g from your data.
and 5.Make the necessary measurements to assess the moment of inertia of the Dural Block 1.Consider the sources of possible errors.Assess them.If you need research for this, do it.Processing the results of the experiment.1 .Set t time for each experiment with a separate load of m (m) and fixed h1 and h2.Identify the accidental loss of time and compare it to the loss of the second.Give the data in the table.The 2ndFor each case, using the formulas (5) and (8), calculate accelerations a and g. Identify errors.3 .Build a graphic dependency of g from 1/m.What does this dependency look like?For which mass is the g value best in line with the table?and the view.the table).Using the obtained dependency to determine the value g.
and 4.Assess the failure of the experiment.Make the conclusions.Two drawings before the first work.

The task
1 .Trace the reversal movement of the property under the action of different dragers at the constant moment of the system's inertia.1.1 Remote the cargo m at a distance R from the turning axis and reach the balanced balance of the property.Measured and record the distance R.
1.2 Do the experiment with the M-mass carrier, measuring the time of the carrier’s fall.The experiment should be repeated 8-10 times, and then mediated the value of t.
1.3 Repeat the study p.1.2 on both scales for 3-4 different values of M.Repeat the p.p.1.2, 1.3 for 3-4 different values of the moment of inertia of the system.Repeat the measurement p.1.2 for 3-4 different mass values M for a system without cargo m.
Make the necessary measurements to determine your own moment of cargo inertia.Processing the results of the experiment
1 .Using the p.p.1.2. and 1.3 find the corner acceleration b and the turn point K that correspond to the movement of each of the trailers on both scales for all the values of the moment of inertia of the system J. Identify errors.The 2ndFor each value R, enter the graphic dependency of the corner acceleration b from the rotative moment K.Determine the inertia moments of the J system and the strengths of the CTER thirty.What are the errors of these sizes?3 .Compare the value of the CTR.Does the size of the CTER depend on the moment of the inertia of the system?The importance of KTER.and 4.The results of defining J for different R values are submitted in a graphic form as the dependency of J(R 2).Consider why it is proposed to build this dependency.After making the results, determine the moment of inertia of the system without cargo J0.How do the results of the experiment coincide with the formula (9)?How does the error amount of the experiment with JB relate?What are the sources of experimental errors?
