Learning Goal: To describe the shape and behavior of cables that are subjected to concentrated and distributed loads. Structures often use flexible cables to support members and to transmit loads between structural members. Because a cable's weight is often significantly smaller than the load it supports, a cable's weight is considered negligible and, therefore, not used in the analysis. In this tutorial, cables are assumed to be perfectly flexible and inextensible. Thus, once the load is applied the geometry of the cable remains fixed and the cable segment can be treated as a rigid body. Part A Cables of negligible weight support the loading shown. (Figure 1) If W₁ = 8.00 lb, W₂ = 78.0 lb, yB = 6.50 ft, yc =8.50 ft, yD = 3.00 ft, and xc = 2.50 ft, find B. Express your answer numerically to three significant figures in feet. ▸ View Available Hint(s) xB = 5.83 ft Submit Previous Answers Part B Correct A cable spans a horizontal distance L = 63.0 ft, supports a uniform load w = 265 lb/ft, and has a sag h = 12.0 ft. (Figure 2) What are the minimum and maximum forces within the cable? Express the minimum and maximum forces within the cable numerically to three significant figures in pounds separated by a comma. ▸ View Available Hint(s) Figure 1 of 2 1 ΑΣΦ Η vec ?

The hollow tube rotates with an 01 = 5 rad/s and 2= 6 rad/s. The sphere A is moving along the shaft (away from the origin) with an = 5 m/s and = 4 m/s². Find the i, j, and k components of the velocity and acceleration of A at this instant if 9 = 35 degrees. Assume r = 6 m. VA = aA = î km/s (1 decimal) k m/s² (no decimals) j+ Ĵ+
