The bar, of length L = 0.850 m, radius R = 0.00600 m, and mass m = 1.000 kg, hits the floor 1 of co Attempts Correct and bounces up, maintaining its vertical orientation. @ Macmillan Learning Assuming that the collision with the floor is elastic and that no rotation occurs, what is the maximum compression A/ of the 6 Question 100% 1 of co Attempts Correct bar? Use the gravitational acceleration g = 9.81 m/s2. 7 Question 97.5% 2 of co Attempts Correct Al = m 8 Question 80% 5 of co Attempts Correct 9 Question 0% 0 of co Attempts 10 Question 0% 0 of co Attempts 11 Question 90% 3 of co Attempts Correct 12 Question 0% 1 of co Attempts 13 Question 100% 1 of co Attempts Correct 14 Question 100% 1 of co Attempts CorrectCheck Answer 10 of 14 Questions @ Assignment Score: 71.6% Resources Ly Give Up? Hint X Question 10 of 14 > 3 Question 100% 1 of co Attempts Correct Two steel wires are connected together, end to end, and attached to a wall. The two wires have the same length and elastic modulus, but the ratio of the radius of the first wire , to the radius of the second wire 2 is 7 : 2. As the wires are initially the 4 Question 45% same length, the midpoint of the combination coincides with the connection point. An applied force then stretches the Macmillan Learning 3 of co Attempts combination by 0.700 mm while the two wires stay connected together. After the wires are stretched, what is 8, the magnitude of the distance from the midpoint to the connection point? 5 Question 100% 1 of co Attempts Correct 6 Question 100% S= mm 1 of co Attempts Correct 7 Question 97.5% 2 of co Attempts Correct 8 Question 80% 5 of co Attempts Correct 9 Question 0% 0 of co Attempts Wire 1 10 Question 0% 0 of co Attempts 11 Question 90% L + L 3 of co Attempts Correct 12 Question 0% 1 of co Attempts Wire 2 13 Question 100% 1 of co Attempts Correct 14 Question 100% L + AL L+ AL, 1 of co Attempts CorrectResume 12 of 14 Questions @ Assignment Score: 71.6% Resources x Give Up?

Find its shear deformation, taking it to have a shear modulus of 1.50 x 10' N/m2. The disk is equivalent to a solid cylinder 0.600 cm high and 4.00 cm in diameter. 4 Question 45% 3 of co Attempts Macmillan Learning Question Credit: OpenStax College Physics 5 Question 100% 1.11 x10- m 1 of co Attempts shear deformation: Correct Incorrect 6 Question 100% 1 of co Attempts Correct 7 Question 97.5% 2 of co Attempts Correct 8 Question 80% 5 of co Attempts Correct 9 Question 0% 0 of co Attempts 10 Question 0% 0 of co Attempts 11 Question 90% 3 of co Attempts Correct 12 Question 0% 1 of co Attempts 13 Question 100% 1 of co Attempts Correct 14 Question 100% 1 of co Attempts Correct
