1. The problem statement, all variables and given/known data A .5 kg block of cheese sits on a level table. The coefficient of static friction is .60. Three strings are tied together in a knot at a point, K. One string is tied to the cheese, the other on a wall at a 30 degree angle, and in the middle of those two strings a mouse hangs from them. What is the maximum mass of the mouse for the cheese and mouse to remain in equilibrium. 2. Relevant equations F = ma Fg = mg 3. The attempt at a solution So, I calculated the Ff of the cheese, being 2.948 N. I know I need to calculate the Ft of the left string, and I think that equation would be for Ftx = (mass mouse)(-9.81) / tan30. I don't know how to calculate Fty, and I don't j=know how to finish the question up. The answer is .16kg.
