You have taken a summerjob at a warehouse and have designed a method to help get heavy packages up a 15° ramp. In your system a package is attached to a rope which runs parallel to the ramp and over a pulley at, the top of the ramp. After passing over the pulley the other end of the rope is attached to a counterweight which hangs straight down. In your design the mass of the counterweight is always adjusted to be twice the mass of the package. Your boss is worried about this pulley system. In particular, she is concerned that the package will be too difficult to handle at the top of the ramp and tells you to calculate its acceleration. To determine the influence of friction between the ramp and the package you run some tests. You find that you can push a 50 kg package with a horizontal force of 250 N at a constant speed along a level floor made of the same material as the ramp. (Hint: Work out the question symbolically and plug in the numbers at the end.) T, a : “M20“ Te may ' ““10““ 'T: m2$'- MLC’V' Discussion # Full Name: (13. Find an expression for the magnitude of the horizontal force F for _ y which m2 does not slip either up or down along the wedge. All surfaces are frictionless. Represent your answers in the simplest possible form in terms of any or all of the following: m1, m2, 6, and any universal physical or mathematical constants. FBD for m; .3 ...

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
