has a diameter of 50 mm and is firmly attached to the rigid supports at A and B when the initial temperature is 50°C. Determine the force P in kN that must be applied to the collar at its midpoint so that, when the final temperature becomes 30°C, the reaction at B is zero. Where: α=12x10^6 m/(m°C), E = 200 GPa and L = 500 m
