A l200-N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end.A l960-N crate hangs from the far end of the beam. Using the data shown in the gure, nd (a) the magnitude of the tension in the wire and the magnitudes of the (a) horizontal and (b) vertical components of the force that the wall exerts on the left end of the beam. 1960 N A wrecking ball (weight = 4750 N) is supported by a boom, which may be assumed to be uniform and has a weight of Support 3340 N.As the drawing shows, a support cable Boom cable runs from the top of the boom to P 48 the tractor. The angle between the support cable and the horizontal is 32, and the angle between the boom and the horizontal is 48. Find the tension in the support cable.A at disk, a solid sphere, and a hollow sphere each have the same mass m and radius r. The three objects are arranged so that an axis of rotation passes through the center of each object. The rotation axis is perpendicular to the plane of the at disk. Which of the three objects has the largest moment of inertia? a) The solid sphere and hollow sphere have the same moment of inertia; and it is the largest. b) The hollow sphere has the largest moment of inertia. c) The solid sphere has the largest moment of inertia. d) The at disk has the largest moment of inertia. e) The at disk and hollow sphere have the same moment of inertia; and it is larger than that of the solid sphere. A ceiling fan is turned on and a net torque of 1.2 N m applied to the blades. The blades have a total moment of inertia of 0.74 kg m2. What is the angular acceleration of the blades?A turntable is a uniform disk with moment of inertia of 2.5kgm2 and radius 0.50 m. It is initially rotating clockwise at an angular speed of l 5rad/s around the axis of rotation, 0. Three external forces, a 25 N and two IO N forces were acting on the disk at the edge of the disk, tangential to the radius, as shown in the gure.The disk comes to rest. a. Calculate the net external torque acting on the disk? b. What is the angular deceleration of the turntable while it is slowing down? F=1ON c. How much work is done on the disk to bring it to rest? F=10N
