A rigid massless link YZ of length 100 mm is connected at one end to another massless link XY of the same length by means of a frictionless hinge at Y and at the other end to a frictionless roller, as shown in the following figure. The link XY is connected to the wall by means of a frictionless hinge at point X. The roller is connected to a massless linear spring with a spring constant 10 kN/m. A point force of 100 N is applied at point Y as shown in the figure. At equilibrium, each of the links XY and YZ makes an angle θ = 30° with the horizontal. Under this situation, the stretch of the spring (in mm) is
