The Uniform Garage Door Has A Mass Of 150 Kg And Is Guided Along Smooth Tracks At Its Ends Lifting Is Done Using The Tw 1 (162.22 KiB) Viewed 11 times

The uniform garage door has a mass of 150 kg and is guided along smooth tracks at its ends. Lifting is done using the two springs, each of which is attached to the anchor bracket at A and to the counterbalance shaft at B and C. As the door is raised, the springs begin to unwind from the shaft, thereby assisting the lift. (Figure 1) Figure 1 of 1 3m 4 m Review Part A If each spring provides a torsional moment of M = (0.850) N-m, where is in radians, determine the angle at which both the left-wound and right-wound spring should be attached so that the door is completely balanced by the springs, i.e., when the door is in the vertical position and is given a slight force upwards, the springs will lift the door along the side tracks to the horizontal plane with no final angular velocity. Note: The elastic potential energy of a torsional spring is Ve=k0², where M = k0 and in this case k = 0.85 N.m/rad. Express your answer using three significant figures.
