Unformatted text preview: 1.4 kg/m . The line will safely support a tension of 5kN . Assume now there is an ice accumulation of 4 kg/m along the cable. 1)[50 points] Determine its tension at the lowest point. 2) [50 points] Determine whether the line with the ice accumulaton is safe. THE UNIVERSITY OF TEXAS AT AUSTIN Department of Aerospace Engineering and Engineering Mechanics EM 306 STATICS - UNIQUE NUMBER 13560 Spring 2009 QUIZ #10 Name: Date: The stationary balloon’s tether is horizontal at point O where it is attached to the truck.The mass per unit length of the tether is 0.45 kg/m . The tether exerts a 50 N horizontal force on the truck. The horizontal distance from point O to point A where the tether is attached to the balloon is 20 m . 1)[50 points] What is the height of point A relative to point O ? 2) [50 points] Determine the magnitudes of the horizontal and vertical components of the force exerted on the balloon at A by the tether....
