Question

1. Pulley Predicament (14 points) Three objects are suspended in the air using massless cords, passing through massless and fixed pulleys as shown. The mass of the middle block mY = 6.50, [kg]. When the system reached equilibrium, it was determined that ? = 52.0° and ? = 38.0°. A. (3 points) Draw the free-body diagrams of blocks X, Y, and Z. B. (6 points) Write down Newton’s 2nd law along the x and y directions for all blocks. C. (2 points) What is the magnitude of mX? D. (2 points) What is the magnitude of mZ? E. (1 point) What would be the magnitude of mX and mZ if ? = ??
