?At a museum, a 1388-kg model aircraft is hung from a lightweight beam of length 12.3 m that is free to pivot about its base and is supported by a massless cable with ? = 19.0° and ? = 52.0°, as shown in the figure. Ignore the mass of the beam. \p
A 15 kg uniform beam, 2 m in length, is supported at it's end by a cable as shown below. The angle between the cable and the horizontal is 45 degrees. 2. Cable Beam Find the horizontal and vertical components of the force from the hinge (left end of the beam) acting on the beam a. b. If the tension in the cord exceeds 115N, the cord will break. Will placing a 5 kg mass at the right end of...
7 The figure shows a uniform horizontal beam (length = 8 m, mass = 20 kg) that is pivoted at the wall, with its far end supported by a cable that makes an angle of 50 degree with the horizontal. If a store's sign (mass = 30 kg) is hung at the end of beam, find all forces on the beam.
The figure shows a uniform, horizontal beam (length = 10.0 m, mass = 30.0 kg) that is held by a horizontal pin (pivoted at the wall), with its far end supported by a cable that makes an angle of 51 degree with the horizontal. A person of mass M stands 3.00 magnitude of 454 N. (a) Calculate the mass M of the person standing on the beam? (b) What are the horizontal and vertical components of the force the pin...
A 0.5 kg street ball is attached to a very light string and hung from the ceiling. The string is 0.78 meters long. The ball is given a horizontal push. The speed after this quick push is 1.4 m/s. The ball then swings like a pendulum. At its highest point, what angle does the string make with the vertical axis?

As shown below, a beam of mass M = 34 kg and length L = 6.8 m is attached to a vertical wall by a hinge and to a horizontal ceiling by a cable. The angle between the beam and the wall is theta = 75 degree, the angle between the cable and the ceiling is phi = 58 degree, and the cable is attached to the beam at a point which is a distance s = 2.2 m from...
1. (10 pts) A uniform 30.0-kg scaffold of length 3.0 m is supported by two light cables, as shown in the figure. A painter A of mass "m" kg stands 0.5 m from the left end of the scaffold. If the tension in the left cable cable is twice that in the right cable, find the tensions in the cables and the mass of the painter A. (Answer the following questions to solve this problem) a. (2 pts) Draw the...
An object with the mass m= 2.0 kg hangs from a cord around a light pulley. The length of the cord between point P and the pulley is L= 2.0 m (Ignore the mass of the vertical section of the cord) a) When the vibrator is set to a frequency of 160 Hz, a standing wave with six loops is formed. What must be the linear mass density of the cord in kg/m? b) How many loops (if any) will...
In the arrangement shown below, an object can be hung from a string (with linear mass density μ = 0.002 00 kg/m) that passes over a light pulley. The string is connected to a vibrator (of constant frequency f), and the length of the string between point P and the pulley is L = 2.30 m. When the mass m of the object is either 9.0 kg or 16.0 kg, standing waves are observed; no standing waves are observed with...
