Do as instructed:a. Simulate m1 = m2 with their respective velocities v1 = v2. Take a screenshot of the simulation. Explain the collision, reaction, and motion of the two masses.Here is the direct link to the simulator - https://ophysics.com/e2.html
The upper beam in Figure is supported at D and a roller at C which separates the upper and lower beams. Determine the values of the reactions at A, B, C, and D in KN. Neglect the weight of the beams.
1. Draw complete, clearly labeled free-body diagrams. All unknown support reactions should be clearly labeled with a variable name. All known values such as weight or applied forces should be clearly labeled with their known values.
Don't need to show equilibrium equations, I just need free-body diagrams. Only solve this text question, not the questions in image.
