Three steel cables jointly support a load of12 kips (see figure). The diameter of the middle cableis 3/4 in. and the diameter of each outer cable is 1/2 in.The tensions in the cables are adjusted so that eachcable carries one-third of the load (i.e., 4 kips). Later,the load is increased by 9 kips to a total load of 21 kips.(a) What percent of the total load is now carried bythe middle cable?(b) What are the stresses σM and σO in the middleand outer cables, respectively? Note: See Table2-1 in Section 2.2 for properties of cables.
