1. Answer the following question about the interactive cantilever modeling system. Consider that a rigid bar is connected to a wall via a free rotating joint, and the spring maintains the bar in a horizontal position, as shown below. Ignore the radius of the bar. 60cm lllllll (x) Incorrect 80cm Specify the resting length of the spring in cm. Assume that mass of the bar is 10 kg and is uniformly distributed, gravitational acceleration is 9.8 m/s^2, and the spring constant is 1000 N/m. Round the answer to the nearest integer, and input the number only. Hint: refer to the original paper if necessary. 0/2 1.
