- Blocks A and B have a mass of 7 kg and 10 kg, respectively, and there are pulleys at C and D. Using the coefficients of static friction indicated, determine the following: 1- The smallest force P which can be applied to the cord that causes impending motion. 2- Does block B spill, flip over, or nothing happen? Prove that.
