The unstretched length of the spring is r so that when the pin P is at the top of the semi-circular channel, the spring is relaxed. When Pis is moved from this position, the spring stretches. The tension force in the spring is given by F = kd where dis the extension from the unstretched length. Consider the following conditions: r = 400 mm, k = 1.4 kN/m, and 0 = 40 degrees. Determine the magnitude of the force the spring exerts on the pin. Express your answer in units of N.
