I have a physics professor for whom I'd like to build a machine. Featured in a problem he is notorious for assigning students, originally from Kleppner and Kolenkow's "Mechanics," the machine causes all three blocks to accelerate, including the large block M1. A picture is featured below.
This problem features frictionless surfaces, massless ropes, and massless frictionless pulleys. I'd like to build the machine for the professor as a thank you gift, but I ask if anybody has suggestions for how to get relatively close to the frictionless and massless constraints above with objects I can realistically build with, e.g. teflon and steel for low-friction surfaces.
Thanks for any advice and suggestions!
