How much work is done by the force in the spring when the slender rod rotates clockwise about the fixed pin support at O from the vertical position (where AB is horizontal) to the horizontal position? The spring has a stiffness of k = 125 N/m and an unstretched length of 0.15 m. Take  d1= 0.29 m and  d2= 0.85 m. Choose the correct answer.  a) 94.9 Joule b) 99.9 Joule c) -99.9 Joule d) 0 Joule e) -94.9 Joule
