I can't finish the last problems on my homework. I asked my teacher and he wouldn't help me, can someone please help me? I'm so confused!

These are the problems

  • Physics problem diagram: a block on a frictionless ramp inclined at 35 degrees, connected over a pulley at the top to a hanging block labeled 200N. Below is the text: In the system above the pulley and ramp are frictionless and the block is in static equilibrium. What is the mass of the block?

  • Diagram of a static equilibrium system: a central knot with a vertical hanging weight W3 below it, two cords at 50 and 35 degrees from the vertical dashed line, passing over pulleys to hanging weights W2 on the left and W1 on the right, with problem text beneath.

Hello greshrop. I suggest you should follow the guidelines here on posting anything related to your homework...
On the pictures you've given it says equilibrium or at rest.. So Summation of Forces will be zero.. Get the summation of Forces Along y and Summation of Forces Along x... sum it to zero.
