Understanding Interaction Forces: Getting Help with a Frustrating Topic

  • Thread starter bubbleeyes
  • Start date
In summary, the conversation is about someone seeking help with understanding the concept of interaction forces, specifically in regards to a frictionless pulley and ramp system. The question asks for the mass of the block in static equilibrium and suggests using a free body diagram and trigonometry to find the forces.

You cannot expect to receive any kind of meaningful help when you are THIS vague. Be specific. If this is a question regarding school work, please use the Homework, Coursework, & Textbook Questions forum. Take note of the rules for that forum before posting.

I just don't get the concept of the whole thing.
Question:
A pulley and ramp are frictionless and the black is in static equilibrium. What is the mass of the block? If the degree is 35 and has 20 kg

Draw a free body diagram (similar to the triangle of the ramp...) Use trigonometry to find the forces (you have one leg of the triangle already, and all the angles...).

When they say the system is in equilibrium, they're saying that the net force is zero: that is, all the forces cancel each other.

Since it's a static equilibrium, the block and anything else being affected by forces in the system is stationary.
