4:45 PM 33% AT&T Notes May 1, 2019 at 4:45 PM Problem 1 a) A uniform beam (5.00 m long, 40.0 kg) is attached to the wall and supported by a cable at the far end, as shown. A 60.0 kg box is placed in the middle of the beanm What is the tension in the cable? b) A wheel in the shape of a solid disk (mass 250 g, radius 30.0 cm) rotates around its central axis, making one revolution every two seconds. A bug (mass 45.0 g) lands on the flat surface of the disk at the outer edge. What is the new rate of rotation of the disk in revolutions per second? (You can treat the bug as a point mass.) c) Consider an identical wheel as the previous problem (without the bug). A force of 18.0 N is applied to the edge of the wheel. This force makes a 30.0° angle with the radius as shown. The wheel can spin on its own central axis. What is the angular acceleration of the wheel? act a Part c 30 °
