1) The spring of modulus k = 3.5 kN/m is stretched 10 mm when the disk center O is in the leftmost position x = 0. Determine the tension T required to position the disk center at x = 150 mm. At that position, what force N is exerted on the horizontal slot ted guide? The mass of the disk is 3 kg. k 3.5 kN/m 45
