Static equilibrium 2 PHYS 2101, P.M.Shikhaliev LSU, Fall 2010 net force applied to the body should be zero net torque applied to the body (relative to any point) should be zero 12.3. Static equilibrium 3 PHYS 2101, P.M.Shikhaliev LSU, Fall 2010 1 2 3 4 In which cases static equilibrium is possible by changing magnitude of forces ? (do not make them zero) Sample problem 1 4 PHYS 2101, P.M.Shikhaliev LSU, Fall 2010 A block with mass M is hanging though two cords with same length. The distances between the hanging points and center of the block are a and b . Find tensions T 1 and T 2 of the cords.
